 * - `aliases` apply all aliases if `virtuals=true`, defaults to true
 * - `virtuals` apply virtual getters (can override `getters` option), defaults to false
 * - `minimize` remove empty objects, defaults to true
 * - `transform` a transform function to apply to the resulting document before returning
 * - `depopulate` depopulate any populated paths, replacing them with their original refs, defaults to false
 * - `versionKey` whether to include the version key, defaults to true
 * - `flattenMaps` convert Maps to POJOs. Useful if you want to JSON.stringify() the result of toObject(), defaults to false
 * - `useProjection` set to `true` to omit fields that are excluded in this document's projection. Unless you specified a projection, this will omit any field that has `select: false` in the schema.
 *
 * #### Getters/Virtuals
 *
 * Example of only applying path getters
 *
 *     doc.toObject({ getters: true, virtuals: false })
 *
 * Example of only applying virtual getters
 *
 *     doc.toObject({ virtuals: true })
 *
 * Example of applying both path and virtual getters
 *
 *     doc.toObject({ getters: true })
 *
 * To apply these options to every document of your schema by default, set your [schemas](#schema_Schema) `toObject` option to the same argument.
 *
 *     schema.set('toObject', { virtuals: true })
 *
 * #### Transform
 *
 * We may need to perform a transformation of the resulting object based on some criteria, say to remove some sensitive information or return a custom object. In this case we set the optional `transform` function.
 *
 * Transform functions receive three arguments
 *
 *     function (doc, ret, options) {}
 *
 * - `doc` The mongoose document which is being converted
 * - `ret` The plain object representation which has been converted
 * - `options` The options in use (either schema options or the options passed inline)
 *
 * #### Example
 *
 *     // specify the transform schema option
 *     if (!schema.options.toObject) schema.options.toObject = {};
 *     schema.options.toObject.transform = function (doc, ret, options) {
 *       // remove the _id of every document before returning the result
 *       delete ret._id;
 *       return ret;
 *     }
 *
 *     // without the transformation in the schema
 *     doc.toObject(); // { _id: 'anId', name: 'Wreck-it Ralph' }
 *
 *     // with the transformation
 *     doc.toObject(); // { name: 'Wreck-it Ralph' }
 *
 * With transformations we can do a lot more than remove properties. We can even return completely new customized objects:
 *
 *     if (!schema.options.toObject) schema.options.toObject = {};
 *     schema.options.toObject.transform = function (doc, ret, options) {
 *       return { movie: ret.name }
 *     }
 *
 *     // without the transformation in the schema
 *     doc.toObject(); // { _id: 'anId', name: 'Wreck-it Ralph' }
 *
 *     // with the transformation
 *     doc.toObject(); // { movie: 'Wreck-it Ralph' }
 *
 * _Note: if a transform function returns `undefined`, the return value will be ignored._
 *
 * Transformations may also be applied inline, overridding any transform set in the options:
 *
 *     function xform (doc, ret, options) {
 *       return { inline: ret.name, custom: true }
 *     }
 *
 *     // pass the transform as an inline option
 *     doc.toObject({ transform: xform }); // { inline: 'Wreck-it Ralph', custom: true }
 *
 * If you want to skip transformations, use `transform: false`:
 *
 *     schema.options.toObject.hide = '_id';
 *     schema.options.toObject.transform = function (doc, ret, options) {
 *       if (options.hide) {
 *         options.hide.split(' ').forEach(function (prop) {
 *           delete ret[prop];
 *         });
 *       }
 *       return ret;
 *     }
 *
 *     const doc = new Doc({ _id: 'anId', secret: 47, name: 'Wreck-it Ralph' });
 *     doc.toObject();                                        // { secret: 47, name: 'Wreck-it Ralph' }
 *     doc.toObject({ hide: 'secret _id', transform: false });// { _id: 'anId', secret: 47, name: 'Wreck-it Ralph' }
 *     doc.toObject({ hide: 'secret _id', transform: true }); // { name: 'Wreck-it Ralph' }
 *
 * If you pass a transform in `toObject()` options, Mongoose will apply the transform
 * to [subdocuments](/docs/subdocs.html) in addition to the top-level document.
 * Similarly, `transform: false` skips transforms for all subdocuments.
 * Note that this behavior is different for transforms defined in the schema:
 * if you define a transform in `schema.options.toObject.transform`, that transform
 * will **not** apply to subdocuments.
 *
 *     const memberSchema = new Schema({ name: String, email: String });
 *     const groupSchema = new Schema({ members: [memberSchema], name: String, email });
 *     const Group = mongoose.model('Group', groupSchema);
 *
 *     const doc = new Group({
 *       name: 'Engineering',
 *       email: 'dev@mongoosejs.io',
 *       members: [{ name: 'Val', email: 'val@mongoosejs.io' }]
 *     });
 *
 *     // Removes `email` from both top-level document **and** array elements
 *     // { name: 'Engineering', members: [{ name: 'Val' }] }
 *     doc.toObject({ transform: (doc, ret) => { delete ret.email; return ret; } });
 *
 * Transforms, like all of these options, are also available for `toJSON`. See [this guide to `JSON.stringify()`](https://thecodebarbarian.com/the-80-20-guide-to-json-stringify-in-javascript.html) to learn why `toJSON()` and `toObject()` are separate functions.
 *
 * See [schema options](/docs/guide.html#toObject) for some more details.
 *

 *

 * @param {Boolean} [options.virtuals=false] if true, apply virtuals, including aliases. Use `{ getters: true, virtuals: false }` to just apply getters, not virtuals
 * @param {Boolean} [options.aliases=true] if `options.virtuals = true`, you can set `options.aliases = false` to skip applying aliases. This option is a no-op if `options.virtuals = false`.
 * @param {Boolean} [options.minimize=true] if true, omit any empty objects from the output
 * @param {Function|null} [options.transform=null] if set, mongoose will call this function to allow you to transform the returned object
 * @param {Boolean} [options.depopulate=false] if true, replace any conventionally populated paths with the original id in the output. Has no affect on virtual populated paths.
 * @param {Boolean} [options.versionKey=true] if false, exclude the version key (`__v` by default) from the output
 * @param {Boolean} [options.flattenMaps=false] if true, convert Maps to POJOs. Useful if you want to `JSON.stringify()` the result of `toObject()`.
 * @param {Boolean} [options.useProjection=false] - If true, omits fields that are excluded in this document's projection. Unless you specified a projection, this will omit any field that has `select: false` in the schema.

 * - `MissingSchemaError`: You tried to access a model with [`mongoose.model()`](api.html#mongoose_Mongoose-model) that was not defined
 * - `DocumentNotFoundError`: The document you tried to [`save()`](api.html#document_Document-save) was not found
 * - `ValidatorError`: error from an individual schema path's validator
 * - `ValidationError`: error returned from [`validate()`](api.html#document_Document-validate) or [`validateSync()`](api.html#document_Document-validateSync). Contains zero or more `ValidatorError` instances in `.errors` property.
 * - `MissingSchemaError`: You called `mongoose.Document()` without a schema
 * - `ObjectExpectedError`: Thrown when you set a nested path to a non-object value with [strict mode set](guide.html#strict).
 * - `ObjectParameterError`: Thrown when you pass a non-object value to a function which expects an object as a paramter
 * - `OverwriteModelError`: Thrown when you call [`mongoose.model()`](api.html#mongoose_Mongoose-model) to re-define a model that was already defined.
 * - `ParallelSaveError`: Thrown when you call [`save()`](api.html#model_Model-save) on a document when the same document instance is already saving.

 *     const Model = mongoose.model('Test', schema);
 *     const doc = new Model({});
 *
 *     // Top-level error is a ValidationError, **not** a ValidatorError
 *     const err = doc.validateSync();
 *     err instanceof mongoose.Error.ValidationError; // true
 *
 *     // A ValidationError `err` has 0 or more ValidatorErrors keyed by the
 *     // path in the `err.errors` property.
 *     err.errors['name'] instanceof mongoose.Error.ValidatorError;
 *
 *     err.errors['name'].kind; // 'required'
 *     err.errors['name'].path; // 'name'
 *     err.errors['name'].value; // undefined
 *
 * Instances of `ValidatorError` have the following properties:
 *
 * - `kind`: The validator's `type`, like `'required'` or `'regexp'`
 * - `path`: The path that failed validation
 * - `value`: The value that failed validation

 * - [capped](/docs/guide.html#capped): bool | number | object - defaults to false
 * - [collection](/docs/guide.html#collection): string - no default
 * - [discriminatorKey](/docs/guide.html#discriminatorKey): string - defaults to `__t`
 * - [id](/docs/guide.html#id): bool - defaults to true
 * - [_id](/docs/guide.html#_id): bool - defaults to true

 * User.updateOne({ _id: _id }, { $set: { email: 'AVENUE@Q.COM' } }); // update to 'avenue@q.com'
 * ```
 *
 * As you can see above, setters allow you to transform the data before it
 * stored in MongoDB, or before executing a query.
 *
 * _NOTE: we could have also just used the built-in `lowercase: true` SchemaType option instead of defining our own function._
 *
 * ```javascript
 * new Schema({ email: { type: String, lowercase: true }})
 * ```
 *
 * Setters are also passed a second argument, the schematype on which the setter was defined. This allows for tailored behavior based on options passed in the schema.
 *
 * ```javascript
 * function inspector (val, priorValue, schematype) {
 *   if (schematype.options.required) {
 *     return schematype.path + ' is required';
 *   } else {
 *     return val;
 *   }
 * }
 *
 * const VirusSchema = new Schema({
 *   name: { type: String, required: true, set: inspector },
 *   taxonomy: { type: String, set: inspector }
 * })
 *
 * const Virus = db.model('Virus', VirusSchema);
 * const v = new Virus({ name: 'Parvoviridae', taxonomy: 'Parvovirinae' });
 *
 * console.log(v.name);     // name is required
 * console.log(v.taxonomy); // Parvovirinae
 * ```
 *
 * You can also use setters to modify other properties on the document. If
 * you're setting a property `name` on a document, the setter will run with
 * `this` as the document. Be careful, in mongoose 5 setters will also run
 * when querying by `name` with `this` as the query.
 *
 * ```javascript
 * const nameSchema = new Schema({ name: String, keywords: [String] });
 * nameSchema.path('name').set(function(v) {
 *   // Need to check if `this` is a document, because in mongoose 5
 *   // setters will also run on queries, in which case `this` will be a
 *   // mongoose query object.
 *   if (this instanceof Document && v != null) {
 *     this.keywords = v.split(' ');
 *   }
 *   return v;
 * });
 * ```

 * @return {SchemaType} this

/**
 * Adds a getter to this schematype.
 *
 * #### Example:
 *
 *     function dob (val) {
 *       if (!val) return val;
 *       return (val.getMonth() + 1) + "/" + val.getDate() + "/" + val.getFullYear();
 *     }
 *
 *     // defining within the schema
 *     const s = new Schema({ born: { type: Date, get: dob })
 *
 *     // or by retreiving its SchemaType
 *     const s = new Schema({ born: Date })
 *     s.path('born').get(dob)
 *
 * Getters allow you to transform the representation of the data as it travels from the raw mongodb document to the value that you see.
 *
 * Suppose you are storing credit card numbers and you want to hide everything except the last 4 digits to the mongoose user. You can do so by defining a getter in the following way:
 *
 *     function obfuscate (cc) {
 *       return '****-****-****-' + cc.slice(cc.length-4, cc.length);
 *     }
 *
 *     const AccountSchema = new Schema({
 *       creditCardNumber: { type: String, get: obfuscate }
 *     });
 *
 *     const Account = db.model('Account', AccountSchema);
 *
 *     Account.findById(id, function (err, found) {
 *       console.log(found.creditCardNumber); // '****-****-****-1234'
 *     });
 *
 * Getters are also passed a second argument, the schematype on which the getter was defined. This allows for tailored behavior based on options passed in the schema.
 *
 *     function inspector (val, priorValue, schematype) {
 *       if (schematype.options.required) {
 *         return schematype.path + ' is required';
 *       } else {
 *         return schematype.path + ' is not';
 *       }
 *     }
 *
 *     const VirusSchema = new Schema({
 *       name: { type: String, required: true, get: inspector },
 *       taxonomy: { type: String, get: inspector }
 *     })
 *
 *     const Virus = db.model('Virus', VirusSchema);
 *
 *     Virus.findById(id, function (err, virus) {

/**
 * Adds validator(s) for this document path.
 *
 * Validators always receive the value to validate as their first argument and
 * must return `Boolean`. Returning `false` or throwing an error means
 * validation failed.
 *
 * The error message argument is optional. If not passed, the [default generic error message template](#error_messages_MongooseError-messages) will be used.
 *
 * #### Examples:
 *
 *     // make sure every value is equal to "something"
 *     function validator (val) {
 *       return val === 'something';
 *     }
 *     new Schema({ name: { type: String, validate: validator }});
 *
 *     // with a custom error message
 *
 *     const custom = [validator, 'Uh oh, {PATH} does not equal "something".']
 *     new Schema({ name: { type: String, validate: custom }});
 *
 *     // adding many validators at a time
 *
 *     const many = [
 *         { validator: validator, msg: 'uh oh' }
 *       , { validator: anotherValidator, msg: 'failed' }
 *     ]
 *     new Schema({ name: { type: String, validate: many }});
 *
 *     // or utilizing SchemaType methods directly:
 *
 *     const schema = new Schema({ name: 'string' });
 *     schema.path('name').validate(validator, 'validation of `{PATH}` failed with value `{VALUE}`');
 *
 * #### Error message templates:
 *
 * From the examples above, you may have noticed that error messages support
 * basic templating. There are a few other template keywords besides `{PATH}`
 * and `{VALUE}` too. To find out more, details are available
 * [here](#error_messages_MongooseError.messages).
 *
 * If Mongoose's built-in error message templating isn't enough, Mongoose
 * supports setting the `message` property to a function.
 *
 *     schema.path('name').validate({
 *       validator: function(v) { return v.length > 5; },
 *       // `errors['name']` will be "name must have length 5, got 'foo'"
 *       message: function(props) {
 *         return `${props.path} must have length 5, got '${props.value}'`;
 *       }
 *     });
 *
 * To bypass Mongoose's error messages and just copy the error message that
 * the validator throws, do this:
 *
 *     schema.path('name').validate({
 *       validator: function() { throw new Error('Oops!'); },
 *       // `errors['name']` will be "Oops!"
 *       message: function(props) { return props.reason.message; }
 *     });
 *
 * #### Asynchronous validation:
 *
 * Mongoose supports validators that return a promise. A validator that returns
 * a promise is called an _async validator_. Async validators run in
 * parallel, and `validate()` will wait until all async validators have settled.
 *
 *     schema.path('name').validate({
 *       validator: function (value) {
 *         return new Promise(function (resolve, reject) {
 *           resolve(false); // validation failed
 *         });
 *       }
 *     });
 *
 * You might use asynchronous validators to retreive other documents from the database to validate against or to meet other I/O bound validation needs.
 *
 * Validation occurs `pre('save')` or whenever you manually execute [document#validate](#document_Document-validate).
 *
 * If validation fails during `pre('save')` and no callback was passed to receive the error, an `error` event will be emitted on your Models associated db [connection](#connection_Connection), passing the validation error object along.
 *
 *     const conn = mongoose.createConnection(..);
 *     conn.on('error', handleError);
 *
 *     const Product = conn.model('Product', yourSchema);
 *     const dvd = new Product(..);
 *     dvd.save(); // emits error on the `conn` above
 *
 * If you want to handle these errors at the Model level, add an `error`
 * listener to your Model as shown below.
 *
 *     // registering an error listener on the Model lets us handle errors more locally
 *     Product.on('error', handleError);
 *
 * @param {RegExp|Function|Object} obj validator function, or hash describing options
 * @param {Function} [obj.validator] validator function. If the validator function returns `undefined` or a truthy value, validation succeeds. If it returns [falsy](https://masteringjs.io/tutorials/fundamentals/falsy) (except `undefined`) or throws an error, validation fails.
 * @param {String|Function} [obj.message] optional error message. If function, should return the error message as a string
 * @param {Boolean} [obj.propsParameter=false] If true, Mongoose will pass the validator properties object (with the `validator` function, `message`, etc.) as the 2nd arg to the validator function. This is disabled by default because many validators [rely on positional args](https://github.com/chriso/validator.js#validators), so turning this on may cause unpredictable behavior in external validators.
 * @param {String|Function} [errorMsg] optional error message. If function, should return the error message as a string
 * @param {String} [type] optional validator type
 * @return {SchemaType} this
 * @api public

 * @param {string|function} [options.foreignField] the foreign field to populate on if this is a populated virtual.
 * @param {boolean} [options.justOne=false] by default, a populated virtual is an array. If you set `justOne`, the populated virtual will be a single doc or `null`.
 * @param {boolean} [options.getters=false] if you set this to `true`, Mongoose will call any custom getters you defined on this virtual
 * @param {boolean} [options.count=false] if you set this to `true`, `populate()` will set this virtual to the number of populated documents, as opposed to the documents themselves, using [`Query#countDocuments()`](./api.html#query_Query-countDocuments)
 * @param {Object|Function} [options.match=null] add an extra match condition to `populate()`
 * @param {Number} [options.limit=null] add a default `limit` to the `populate()` query
 * @param {Number} [options.skip=null] add a default `skip` to the `populate()` query
 * @param {Number} [options.perDocumentLimit=null] For legacy reasons, `limit` with `populate()` may give incorrect results because it only executes a single query for every document being populated. If you set `perDocumentLimit`, Mongoose will ensure correct `limit` per document by executing a separate query for each document to `populate()`. For example, `.find().populate({ path: 'test', perDocumentLimit: 2 })` will execute 2 additional queries if `.find()` returns 2 documents.

 * Javascript performs bit-operations.  For operations like addition and
 * multiplication, we split each number into 16 bit pieces, which can easily be
 * multiplied within Javascript's floating-point representation without overflow
 * or change in sign.
 * In the algorithms below, we frequently reduce the negative case to the
 * positive case by negating the input(s) and then post-processing the result.
 * Note that we must ALWAYS check specially whether those values are MIN_VALUE
 * (-2^63) because -MIN_VALUE == MIN_VALUE (since 2^63 cannot be represented as
 * a positive number, it overflows back into a negative).  Not handling this
 * case would often result in infinite recursion.
 * Common constant values ZERO, ONE, NEG_ONE, etc. are found as static properties on this class.

/**
 * Declare and/or execute this query as an update() operation. By default,
 * `update()` only modifies the _first_ document that matches `criteria`.
 *
 * _All paths passed that are not $atomic operations will become $set ops._
 *
 * ####Example
 *
 *     mquery({ _id: id }).update({ title: 'words' }, ...)
 *
 * becomes
 *
 *     collection.update({ _id: id }, { $set: { title: 'words' }}, ...)
 *
 * ####Note
 *
 * Passing an empty object `{}` as the doc will result in a no-op unless the `overwrite` option is passed. Without the `overwrite` option set, the update operation will be ignored and the callback executed without sending the command to MongoDB so as to prevent accidently overwritting documents in the collection.
 *
 * ####Note
 *
 * The operation is only executed when a callback is passed. To force execution without a callback (which would be an unsafe write), we must first call update() and then execute it by using the `exec()` method.
 *
 *     var q = mquery(collection).where({ _id: id });
 *     q.update({ $set: { name: 'bob' }}).update(); // not executed
 *
 *     var q = mquery(collection).where({ _id: id });
 *     q.update({ $set: { name: 'bob' }}).exec(); // executed as unsafe
 *
 *     // keys that are not $atomic ops become $set.
 *     // this executes the same command as the previous example.
 *     q.update({ name: 'bob' }).where({ _id: id }).exec();
 *
 *     var q = mquery(collection).update(); // not executed
 *
 *     // overwriting with empty docs
 *     var q.where({ _id: id }).setOptions({ overwrite: true })
 *     q.update({ }, callback); // executes
 *
 *     // multi update with overwrite to empty doc
 *     var q = mquery(collection).where({ _id: id });
 *     q.setOptions({ multi: true, overwrite: true })
 *     q.update({ });
 *     q.update(callback); // executed

 *     // multi updates
 *     mquery()
 *       .collection(coll)

// a transform stream is a readable/writable stream where you do
// something with the data.  Sometimes it's called a "filter",
// but that's not a great name for it, since that implies a thing where
// some bits pass through, and others are simply ignored.  (That would
// be a valid example of a transform, of course.)
//
// While the output is causally related to the input, it's not a
// necessarily symmetric or synchronous transformation.  For example,
// a zlib stream might take multiple plain-text writes(), and then
// emit a single compressed chunk some time in the future.
//
// Here's how this works:
//
// The Transform stream has all the aspects of the readable and writable
// stream classes.  When you write(chunk), that calls _write(chunk,cb)
// internally, and returns false if there's a lot of pending writes
// buffered up.  When you call read(), that calls _read(n) until
// there's enough pending readable data buffered up.
//
// In a transform stream, the written data is placed in a buffer.  When
// _read(n) is called, it transforms the queued up data, calling the
// buffered _write cb's as it consumes chunks.  If consuming a single
// written chunk would result in multiple output chunks, then the first
// outputted bit calls the readcb, and subsequent chunks just go into
// the read buffer, and will cause it to emit 'readable' if necessary.
//
// This way, back-pressure is actually determined by the reading side,
// since _read has to be called to start processing a new chunk.  However,
// a pathological inflate type of transform can cause excessive buffering
// here.  For example, imagine a stream where every byte of input is
// interpreted as an integer from 0-255, and then results in that many
// bytes of output.  Writing the 4 bytes {ff,ff,ff,ff} would result in
// 1kb of data being output.  In this case, you could write a very small
// amount of input, and end up with a very large amount of output.  In
// such a pathological inflating mechanism, there'd be no way to tell
// the system to stop doing the transform.  A single 4MB write could
// cause the system to run out of memory.
//
// However, even in such a pathological case, only a single written chunk
// would be consumed, and then the rest would wait (un-transformed) until
// the results of the previous transformed chunk were consumed.
