/**
|
|
* Model behavior base class.
|
|
*
|
|
* Defines the Behavior interface, and contains common model interaction functionality. Behaviors
|
|
* allow you to simulate mixins, and create resuable blocks of application logic, that can be reused across
|
|
* several models. Behaviors also provide a way to hook into model callbacks and augment their behavior.
|
|
*
|
|
* ### Mixin methods
|
|
*
|
|
* Behaviors can provide mixin like features by declaring public methods. These methods should expect
|
|
* the model instance to be shifted onto the parameter list.
|
|
*
|
|
* {{{
|
|
* function doSomething($model, $arg1, $arg2) {
|
|
* //do something
|
|
* }
|
|
* }}}
|
|
*
|
|
* Would be called like `$this->Model->doSomething($arg1, $arg2);`.
|
|
*
|
|
* ### Mapped methods
|
|
*
|
|
* Behaviors can also define mapped methods. Mapped methods use pattern matching for method invocation. This
|
|
* allows you to create methods similar to Model::findAllByXXX methods on your behaviors. Mapped methods need to
|
|
* be declared in your behaviors `$mapMethods` array. The method signature for a mapped method is slightly different
|
|
* than a normal behavior mixin method.
|
|
*
|
|
* {{{
|
|
* var $mapMethods = array('/do(\w+)/' => 'doSomething');
|
|
*
|
|
* function doSomething($model, $method, $arg1, $arg2) {
|
|
* //do something
|
|
* }
|
|
* }}}
|
|
*
|
|
* The above will map every doXXX() method call to the behavior. As you can see, the model is
|
|
* still the first parameter, but the called method name will be the 2nd parameter. This allows
|
|
* you to munge the method name for additional information, much like Model::findAllByXX.
|
|
*

|
* @package cake.libs.model

* @see Model::$actsAs

* @see BehaviorCollection::load()
