Returns
A reference to the DataSource object, or null if creation failed
enumConnectionObjects() public ¶
enumConnectionObjects( )
Return a list of connections

sourceList() public ¶
sourceList( )
Gets the list of available DataSource connections
Returns
List of available connections
Methods inherited from Object
Object() public ¶
Object( )
A hack to support __construct() on PHP 4 Hint: descendant classes have no PHP4 class_name() constructors, so this constructor gets called first and calls the top-layer __construct() which (if present) should call parent::__construct()
Returns
__openPersistent() public ¶
__openPersistent( string $name , string $type = null )
Open the persistent class file for reading Used by Object::_persist()
Parameters
- string $name
- Name of persisted class
- string $type optional null
- Type of persistance (e.g: registry)
_persist() public ¶

Parameters
- string $name
- name of the class to persist
- string $return
- $object the object to persist
- $object
- $type optional null
Returns
Success
_savePersistent() public ¶
_savePersistent( string $name , object $object )
You should choose a unique name for the persistent file
