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:
<?php
$driver =& Structures_DataGrid::dataSourceFactory($source);
?>
Detect the source type and load the appropriate driver with custom options:
<?php
$driver =& Structures_DataGrid::dataSourceFactory($source, $options);
?>
Load a driver for an explicit type (faster, bypasses detection routine):
<?php
$driver =& Structures_DataGrid::dataSourceFactory($source, $options, $type);
?>
