/**
* 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 $.fn.DataTable.Api( 'table.dataTable' );

/**
* DataTables can be instructed to load data to display in the table from a
* Ajax source. This option defines how that Ajax call is made and where to.
*
* The `ajax` property has three different modes of operation, depending on
* how it is defined. These are:
*
* * `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.

* buttons are displayed in the document, while the functions here tell it
* what buttons to display. This is done by returning an array of button
* descriptions (what each button will do).
*
* Pagination types (the four built in options and any additional plug-in
* options defined here) can be used through the `paginationType`
* initialisation parameter.
*
* The functions defined take two parameters:
*
* 1. `{int} page` The current page index
* 2. `{int} pages` The number of pages in the table
*
* Each function is expected to return an array where each element of the
* array can be one of:
*
* * `first` - Jump to first page when activated
* * `last` - Jump to last page when activated
* * `previous` - Show previous page when activated
* * `next` - Show next page when activated
* * `{int}` - Show page of the index given
* * `{array}` - A nested array containing the above elements to add a
* containing 'DIV' element (might be useful for styling).
*
* Note that DataTables v1.9- used this object slightly differently whereby
* an object with two functions would be defined for each plug-in. That
* ability is still supported by DataTables 1.10+ to provide backwards
* compatibility, but this option of use is now decremented and no longer
* documented in DataTables 1.10+.

/**
* Ordering plug-ins - custom data source
*
* The extension options for ordering of data available here is complimentary
* to the default type based ordering that DataTables typically uses. It
* allows much greater control over the the data that is being used to
* order a column, but is necessarily therefore more complex.
*
* 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:
*
* * `{array}` Data for the column to be ordering upon
*
* @type array
*
* @example
* // Ordering using `input` node values
* $.fn.dataTable.ext.order['dom-text'] = function ( settings, col )
* {
* return this.api().column( col, {order:'index'} ).nodes().map( function ( td, i ) {
* return $('input', td).val();

* can also make use of the column type if required).

*
* 1. `{*}` Data from the column cell to be analysed
* 2. `{settings}` DataTables settings object. This can be used to
* perform context specific type detection - for example detection
* based on language settings such as using a comma for a decimal

* be required
*
* Each function is expected to return:
*

* // Currency type detection plug-in:

*
* Note that is a search is not defined for a column of a given type,
* no search formatting will be performed.
*
* Pre-processing of searching data plug-ins - When you assign the sType
* for a column (or have it automatically detected for you by DataTables
* or a type detection plug-in), you will typically be using this for
* custom sorting, but it can also be used to provide custom searching
* by allowing you to pre-processing the data and returning the data in
* the format that should be searched upon. This is done by adding
* functions this object with a parameter name which matches the sType
* for that target column. This is the corollary of <i>afnSortData</i>
* for searching data.
*
* The functions defined take a single parameter:
*
* 1. `{*}` Data from the column cell to be prepared for searching
*
* Each function is expected to return:
*
* * `{string|null}` Formatted string that will be used for the searching.

/**
* Type based ordering.
*
* The column type tells DataTables what ordering to apply to the table
* when a column is sorted upon. The order for each type that is defined,
* is defined by the functions available in this object.
*
* Each ordering option can be described by three properties added to
* this object:
*
* * `{type}-pre` - Pre-formatting function
* * `{type}-asc` - Ascending order function
* * `{type}-desc` - Descending order function
*
* All three can be used together, only `{type}-pre` or only
* `{type}-asc` and `{type}-desc` together. It is generally recommended
* that only `{type}-pre` is used, as this provides the optimal
* implementation in terms of speed, although the others are provided
* for compatibility with existing Javascript sort functions.
*
* `{type}-pre`: Functions defined take a single parameter:
*
* 1. `{*}` Data from the column cell to be prepared for ordering
*
* And return:
*
* * `{*}` Data to be sorted upon
*
* `{type}-asc` and `{type}-desc`: Functions are typical Javascript sort
* functions, taking two parameters:
*
* 1. `{*}` Data to compare to the second parameter
* 2. `{*}` Data to compare to the first parameter
*
* And returning:
*
* * `{*}` Ordering match: <0 if first parameter should be sorted lower
* than the second parameter, ===0 if the two parameters are equal and
* >0 if the first parameter should be sorted height than the second
* parameter.

/**
* Responsive is a plug-in for the DataTables library that makes use of
* DataTables' ability to change the visibility of columns, changing the
* visibility of columns so the displayed columns fit into the table container.
* The end result is that complex tables will be dynamically adjusted to fit
* into the viewport, be it on a desktop, tablet or mobile browser.
*
* Responsive for DataTables has two modes of operation, which can used
* individually or combined:
*
* * Class name based control - columns assigned class names that match the
* breakpoint logic can be shown / hidden as required for each breakpoint.
* * Automatic control - columns are automatically hidden when there is no
* room left to display them. Columns removed from the right.
*
* In additional to column visibility control, Responsive also has built into
* options to use DataTables' child row display to show / hide the information
* from the table that has been hidden. There are also two modes of operation
* for this child row display:
*
* * Inline - when the control element that the user can use to show / hide
* child rows is displayed inside the first column of the table.
* * Column - where a whole column is dedicated to be the show / hide control.
*
* Initialisation of Responsive is performed by:
*
* * Adding the class `responsive` or `dt-responsive` to the table. In this case
* Responsive will automatically be initialised with the default configuration
* options when the DataTable is created.
* * Using the `responsive` option in the DataTables configuration options. This
* can also be used to specify the configuration options, or simply set to
* `true` to use the defaults.
*
* @class
* @param {object} settings DataTables settings object for the host table
* @param {object} [opts] Configuration options
* @requires jQuery 1.7+
* @requires DataTables 1.10.3+

/**
* Scroller is a virtual rendering plug-in for DataTables which allows large
* datasets to be drawn on screen every quickly. What the virtual rendering means
* is that only the visible portion of the table (and a bit to either side to make
* the scrolling smooth) is drawn, while the scrolling container gives the
* visual impression that the whole table is visible. This is done by making use
* of the pagination abilities of DataTables and moving the table around in the
* scrolling container DataTables adds to the page. The scrolling container is
* forced to the height it would be for the full table display using an extra
* element.
*
* Note that rows in the table MUST all be the same height. Information in a cell
* which expands on to multiple lines will cause some odd behaviour in the scrolling.
*
* Scroller is initialised by simply including the letter 'S' in the sDom for the
* table you want to have this feature enabled on. Note that the 'S' must come
* AFTER the 't' parameter in `dom`.
*
* Key features include:
* <ul class="limit_length">
* <li>Speed! The aim of Scroller for DataTables is to make rendering large data sets fast</li>
* <li>Full compatibility with deferred rendering in DataTables for maximum speed</li>
* <li>Display millions of rows</li>
* <li>Integration with state saving in DataTables (scrolling position is saved)</li>

/*
Select is a collection of API methods, event handlers, event emitters and
buttons (for the `Buttons` extension) for DataTables. It provides the following
features, with an overview of how they are implemented:
## Selection of rows, columns and cells. Whether an item is selected or not is
stored in:
* rows: a `_select_selected` property which contains a boolean value of the
DataTables' `aoData` object for each row
* columns: a `_select_selected` property which contains a boolean value of the
DataTables' `aoColumns` object for each column
* cells: a `_selected_cells` property which contains an array of boolean values
of the `aoData` object for each row. The array is the same length as the
columns array, with each element of it representing a cell.
This method of using boolean flags allows Select to operate when nodes have not
been created for rows / cells (DataTables' defer rendering feature).
## API methods
A range of API methods are available for triggering selection and de-selection
of rows. Methods are also available to configure the selection events that can
be triggered by an end user (such as which items are to be selected). To a large
extent, these of API methods *is* Select. It is basically a collection of helper
functions that can be used to select items in a DataTable.
Configuration of select is held in the object `_select` which is attached to the
DataTables settings object on initialisation. Select being available on a table
is not optional when Select is loaded, but its default is for selection only to
be available via the API - so the end user wouldn't be able to select rows
without additional configuration.
The `_select` object contains the following properties:
```
{
items:string - Can be `rows`, `columns` or `cells`. Defines what item
will be selected if the user is allowed to activate row
selection using the mouse.
style:string - Can be `none`, `single`, `multi` or `os`. Defines the
interaction style when selecting items
blurable:boolean - If row selection can be cleared by clicking outside of
the table
toggleable:boolean - If row selection can be cancelled by repeated clicking
on the row
info:boolean - If the selection summary should be shown in the table
information elements
}
```
In addition to the API methods, Select also extends the DataTables selector
options for rows, columns and cells adding a `selected` option to the selector
options object, allowing the developer to select only selected items or
unselected items.
## Mouse selection of items
Clicking on items can be used to select items. This is done by a simple event
handler that will select the items using the API methods.
