*
* This type of ordering is useful if you want to do ordering based on data
* live from the DOM (for example the contents of an 'input' element) rather
* than just the static string that DataTables knows of.
*
* The way these plug-ins work is that you create an array of the values you
* wish to be ordering for the column in question and then return that
* array. The data in the array much be in the index order of the rows in
* the table (not the currently ordering order!). Which order data gathering
* function is run here depends on the `dt-init columns.orderDataType`
* parameter that is used for the column (if any).
*
* The functions defined take two parameters:
*
* 1. `{object}` DataTables settings object: see

* 2. `{int}` Target column index
*

/**
* DataTables API class - used to control and interface with one or more
* DataTables enhanced tables.
*
* The API class is heavily based on jQuery, presenting a chainable interface
* that you can use to interact with tables. Each instance of the API class has
* a "context" - i.e. the tables that it will operate on. This could be a single
* table, all tables on a page or a sub-set thereof.
*
* Additionally the API is designed to allow you to easily work with the data in
* the tables, retrieving and manipulating it as required. This is done by
* presenting the API class as an array like interface. The contents of the
* array depend upon the actions requested by each method (for example
* `rows().nodes()` will return an array of nodes, while `rows().data()` will
* return an array of objects or arrays depending upon your table's
* configuration). The API object has a number of array like methods (`push`,
* `pop`, `reverse` etc) as well as additional helper methods (`each`, `pluck`,
* `unique` etc) to assist your working with the data held in a table.
*
* Most methods (those which return an Api instance) are chainable, which means
* the return from a method call also has all of the methods available that the
* top level object had. For example, these two calls are equivalent:
*
* // Not chained
* api.row.add( {...} );
* api.draw();
*
* // Chained
* api.row.add( {...} ).draw();
*
* @class DataTable.Api
* @param {array|object|string|jQuery} context DataTable identifier. This is
* used to define which DataTables enhanced tables this API will operate on.
* Can be one of:
*
* * `string` - jQuery selector. Any DataTables' matching the given selector
* with be found and used.
* * `node` - `TABLE` node which has already been formed into a DataTable.
* * `jQuery` - A jQuery object of `TABLE` nodes.
* * `object` - DataTables settings object
* @param {array} [data] Data to initialise the Api instance with.
*
* @example
* // Direct initialisation during DataTables construction
* var api = $('#example').DataTable();
*
* @example
* // Initialisation using a DataTables jQuery object
* var api = $('#example').dataTable().api();
*
* @example
* // Initialisation as a constructor
* var api = new DataTable.Api( 'table.dataTable' );

* DataTables can be instructed to load data to display in the table from a

*
* * `string` - Set the URL from where the data should be loaded from.
* * `object` - Define properties for `jQuery.ajax`.
* * `function` - Custom data get function
*
* `string`
* --------
*
* As a string, the `ajax` property simply defines the URL from which
* DataTables will load data.
*
* `object`
* --------
*
* As an object, the parameters in the object are passed to
* [jQuery.ajax](https://api.jquery.com/jQuery.ajax/) allowing fine control
* of the Ajax request. DataTables has a number of default parameters which
* you can override using this option. Please refer to the jQuery
* documentation for a full description of the options available, although
* the following parameters provide additional options in DataTables or
* require special consideration:
*
* * `data` - As with jQuery, `data` can be provided as an object, but it
* can also be used as a function to manipulate the data DataTables sends
* to the server. The function takes a single parameter, an object of
* parameters with the values that DataTables has readied for sending. An
* object may be returned which will be merged into the DataTables
* defaults, or you can add the items to the object that was passed in and
* not return anything from the function. This supersedes `fnServerParams`
* from DataTables 1.9-.
*
* * `dataSrc` - By default DataTables will look for the property `data` (or
* `aaData` for compatibility with DataTables 1.9-) when obtaining data
* from an Ajax source or for server-side processing - this parameter
* allows that property to be changed. You can use Javascript dotted
* object notation to get a data source for multiple levels of nesting, or
* it my be used as a function. As a function it takes a single parameter,
* the JSON returned from the server, which can be manipulated as
* required, with the returned value being that used by DataTables as the
* data source for the table.
*
* * `success` - Should not be overridden it is used internally in
* DataTables. To manipulate / transform the data returned by the server
* use `ajax.dataSrc`, or use `ajax` as a function (see below).
*
* `function`
* ----------
*
* As a function, making the Ajax call is left up to yourself allowing
* complete control of the Ajax request. Indeed, if desired, a method other
* than Ajax could be used to obtain the required data, such as Web storage
* or an AIR database.
*
* The function is given four parameters and no return is required. The
* parameters are:
*
* 1. _object_ - Data to send to the server
* 2. _function_ - Callback function that must be executed when the required
* data has been obtained. That data should be passed into the callback
* as the only parameter
* 3. _object_ - DataTables settings object for the table

* This property can be used to read data from any data source property,

* * `integer` - treated as an array index for the data source. This is the
* default that DataTables uses (incrementally increased for each column).
* * `string` - read an object property from the data source. There are
* three 'special' options that can be used in the string to alter how
* DataTables reads the data from the source object:
* * `.` - Dotted Javascript notation. Just as you use a `.` in
* Javascript to read from nested objects, so to can the options
* specified in `data`. For example: `browser.version` or
* `browser.name`. If your object parameter name contains a period, use
* `\\` to escape it - i.e. `first\\.name`.
* * `[]` - Array notation. DataTables can automatically combine data
* from and array source, joining the data with the characters provided
* between the two brackets. For example: `name[, ]` would provide a
* comma-space separated list from the source array. If no characters
* are provided between the brackets, the original array source is
* returned.
* * `()` - Function notation. Adding `()` to the end of a parameter will
* execute a function of the name given. For example: `browser()` for a
* simple function on the data source, `browser.version()` for a
* function in a nested property or even `browser().version` to get an
* object property if the function called returns an object. Note that
* function notation is recommended for use in `render` rather than
* `data` as it is much simpler to use as a renderer.
* * `null` - use the original data source for the row rather than plucking
* data directly from it. This action has effects on two other
* initialisation options:
* * `defaultContent` - When null is given as the `data` option and
* `defaultContent` is specified for the column, the value defined by
* `defaultContent` will be used for the cell.
* * `render` - When null is used for the `data` option and the `render`
* option is specified for the column, the whole data source for the
* row is used for the renderer.
* * `function` - the function given will be executed whenever DataTables
* needs to set or get the data for a cell in the column. The function
* takes three parameters:
* * Parameters:
* * `{array|object}` The data source for the row
* * `{string}` The type call data requested - this will be 'set' when
* setting data or 'filter', 'display', 'type', 'sort' or undefined
* when gathering data. Note that when `undefined` is given for the
* type DataTables expects to get the raw data for the object back<
* * `{*}` Data to set when the second parameter is 'set'.
* * Return:
* * The return value from the function is not required when 'set' is
* the type of call, but otherwise the return is what will be used
* for the data requested.
*
* Note that `data` is a getter and setter option. If you just require
* formatting of data for output, you will likely want to use `render` which
* is simply a getter and thus simpler to use.
*
* Note that prior to DataTables 1.9.2 `data` was called `mDataProp`. The
* name change reflects the flexibility of this property and is consistent
* with the naming of mRender. If 'mDataProp' is given, then it will still
* be used by DataTables, as it automatically maps the old name to the new
* if required.

* `data` which is read / write (then as such more complex). Like `data`
* this option can be given in a number of different ways to effect its

* * `integer` - treated as an array index for the data source. This is the

* simple function on the data source, `browser.version()` for a
* function in a nested property or even `browser().version` to get an
* object property if the function called returns an object.
* * `object` - use different data for the different data types requested by
* DataTables ('filter', 'display', 'type' or 'sort'). The property names
* of the object is the data type the property refers to and the value can
* defined using an integer, string or function using the same rules as
* `render` normally does. Note that an `_` option _must_ be specified.
* This is the default value to use if you haven't specified a value for
* the data type requested by DataTables.
* * `function` - the function given will be executed whenever DataTables
* needs to set or get the data for a cell in the column. The function
* takes three parameters:
* * Parameters:
* * {array|object} The data source for the row (based on `data`)

/**
* Helpers for `columns.render`.
*
* The options defined here can be used with the `columns.render` initialisation
* option to provide a display renderer. The following functions are defined:
*
* * `moment` - Uses the MomentJS library to convert from a given format into another.
* This renderer has three overloads:
* * 1 parameter:
* * `string` - Format to convert to (assumes input is ISO8601 and locale is `en`)
* * 2 parameters:
* * `string` - Format to convert from
* * `string` - Format to convert to. Assumes `en` locale
* * 3 parameters:
* * `string` - Format to convert from
* * `string` - Format to convert to
* * `string` - Locale
* * `number` - Will format numeric data (defined by `columns.data`) for
* display, retaining the original unformatted data for sorting and filtering.
* It takes 5 parameters:
* * `string` - Thousands grouping separator
* * `string` - Decimal point indicator
* * `integer` - Number of decimal points to show
* * `string` (optional) - Prefix.
* * `string` (optional) - Postfix (/suffix).
* * `text` - Escape HTML to help prevent XSS attacks. It has no optional
* parameters.
*
* @example
* // Column definition using the number renderer
* {
* data: "salary",
* render: $.fn.dataTable.render.number( '\'', '.', 0, '$' )
* }
