Class AclComponent
Access Control List factory class.
Uses a strategy pattern to allow custom ACL implementations to be used with the same component interface.
You can define by changing Configure::write('Acl.classname', 'DbAcl'); in your core.php. Concrete ACL
implementations should extend AclBase and implement the methods it defines.

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 ¶
_persist( string $name , string $return , $object , $type = null )
Checks for a persistent class file, if found file is opened and true returned If file is not found a file is created and false returned If used in other locations of the model you should choose a unique name for the persistent file There are many uses for this method, see manual for examples
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
There are many uses for this method, see manual for examples
Parameters
- string $name

true on save, throws error if file can not be created
