Structures_DataGrid::dataSourceFactory()

Structures_DataGrid::dataSourceFactory()  -- Datasource driver Factory

Synopsis

require_once 'Structures/DataGrid.php';

Structures_DataGrid_DataSource|PEAR_Error& Structures_DataGrid::dataSourceFactory (mixed $source, array [$options = array()], string [$type = NULL])

Описание

A clever method which loads and instantiate data source drivers.

Can be called in various ways:

Detect the source type and load the appropriate driver with default options: 

$driver =& Structures_DataGrid::dataSourceFactory($source);

Detect the source type and load the appropriate driver with custom options: 

$driver =& Structures_DataGrid::dataSourceFactory($source, $options);

Load a driver for an explicit type (faster, bypasses detection routine): 

$driver =& Structures_DataGrid::dataSourceFactory($source, $options, $type);

Параметр

mixed $source

array $options

An associative array of the form: array(optionName => optionValue, ...)

string $type

The data source type constant (of the form DATAGRID_SOURCE_*)

Возвращаемое значение

Throws
