+ * 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();

+ * 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](http://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. This supersedes `sAjaxDataProp` from
+ * DataTables 1.9-.
+ *
+ * * `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
+ *
+ * Note that this supersedes `fnServerData` from DataTables 1.9-.

+ * 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.

+ * 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
+ * {@link DataTable.models.oSettings}
+ * 2. `{int}` Target column index
+ *
+ * Each function is expected to return an array:
