Class BehaviorCollection

attach()source public

attach( string $behavior , array $config array() )

Backwards compatible alias for load()

Deprecated

3.0.0 Will be removed in 3.0. Replaced with load().

Parameters

string $behavior

Behavior name.

array $config optional array()

Configuration options.

detach()source public

detach( string $name )

Backwards compatible alias for unload()

Deprecated

3.0.0 Will be removed in 3.0. Use unload instead.

Parameters

string $name

Name of behavior

dispatchMethod()source public

dispatchMethod( Model $model , string $method , array $params array() , boolean $strict false )

Dispatches a behavior method. Will call either normal methods or mapped methods.

If a method is not handled by the BehaviorCollection, and $strict is false, a special return of array('unhandled') will be returned to signal the method was not found.

Parameters

Model $model

The model the method was originally called on.

string $method

The method called.

array $params optional array()

Parameters for the called method.

boolean $strict optional false

If methods are not found, trigger an error.

Returns

array
All methods for all behaviors attached to this object

hasMethod()source public

hasMethod( string $method , boolean $callback false )

Check to see if a behavior in this collection implements the provided method. Will also check mappedMethods.

Parameters

string $method

The method to find.

boolean $callback optional false

Return the callback for the method.

Returns

mixed

If $callback is false, a boolean will be returned, if its true, an array containing callback information will be returned. For mapped methods the array will have 3 elements.

implementedEvents()source public

implementedEvents( )

Returns the implemented events that will get routed to the trigger function in order to dispatch them separately on each behavior

Returns

array

Implementation of

CakeEventListener::implementedEvents()

init()source public

init( string $modelName , array $behaviors array() )

Attaches a model object and loads a list of behaviors

Parameters

string $modelName

Model name.

array $behaviors optional array()

Behaviors list.

load()source public

load( string $behavior , array $config array() )

Loads a behavior into the collection. You can use use $config['enabled'] = false to load a behavior with callbacks disabled. By default callbacks are enabled. Disable behaviors can still be used as normal.

You can alias your behavior as an existing behavior by setting the 'className' key, i.e.,

public $actsAs = array(
  'Tree' => array(
    'className' => 'AliasedTree'
  );
);

All calls to the Tree behavior would use AliasedTree instead.

Parameters

string $behavior

CamelCased name of the behavior to load

array $config optional array()

Behavior configuration parameters

Returns

boolean
True on success, false on failure

Throws

MissingBehaviorException
when a behavior could not be found.

methods()source public

methods( )

Gets the method list for attached behaviors, i.e. all public, non-callback methods. This does not include mappedMethods.

Returns

array
All public methods for all behaviors attached to this collection

unload()source public

unload( string $name )

Detaches a behavior from a model

Parameters

string $name

CamelCased name of the behavior to unload

Overrides

ObjectCollection::unload()

__get()source public

__get( string $name )

Provide public read access to the loaded objects

Parameters

string $name

Name of property to read

Returns

mixed

__isset()source public

__isset( string $name )

Provide isset access to _loaded

Parameters

string $name

Name of object being checked.

Returns

boolean

attached()source public

attached( string $name null )

Gets the list of attached objects, or, whether the given object is attached

Deprecated

3.0.0 Will be removed in 3.0. Use loaded instead.

Parameters

string $name optional null

Optional. The name of the object to check the status of. If omitted, returns an array of currently-attached objects

Returns

mixed

If $name is specified, returns the boolean status of the corresponding object. Otherwise, returns an array of all attached objects.

disable()source public

disable( string|array $name )

Disables callbacks on an object or array of objects. Public object methods are still callable as normal.

Parameters

string|array $name

CamelCased name of the objects(s) to disable (string or array)

enable()source public

enable( string|array $name , boolean $prioritize true )

Enables callbacks on an object or array of objects

Parameters

string|array $name

CamelCased name of the object(s) to enable (string or array)

boolean $prioritize optional true

Prioritize enabled list after enabling object(s)

enabled()source public

enabled( string $name null )

Gets the list of currently-enabled objects, or, the current status of a single objects

Parameters

string $name optional null

Optional. The name of the object to check the status of. If omitted, returns an array of currently-enabled object

Returns

mixed

If $name is specified, returns the boolean status of the corresponding object. Otherwise, returns an array of all enabled objects.

loaded()source public

loaded( string $name null )

Gets the list of loaded objects, or, whether the given object is loaded

Parameters

string $name optional null

Optional. The name of the object to check the status of. If omitted, returns an array of currently-loaded objects

Returns

mixed

If $name is specified, returns the boolean status of the corresponding object. Otherwise, returns an array of all loaded objects.

normalizeObjectArray()source public static

normalizeObjectArray( array $objects )

Normalizes an object array, creates an array that makes lazy loading easier

Parameters

array $objects

Array of child objects to normalize.

Returns

array
Array of normalized objects.

prioritize()source public

prioritize( )

Prioritize list of enabled object

Returns

array
Prioritized list of object

set()source public

set( string $name null , CakeObject $object null )

Adds or overwrites an instantiated object to the collection

Parameters

string $name optional null

Name of the object

CakeObject $object optional null

The object to use

Returns

array
Loaded objects

setPriority()source public

setPriority( string|array $name , integer|null $priority null )

Set priority for an object or array of objects

Parameters

string|array $name

CamelCased name of the object(s) to enable (string or array) If string the second param $priority is used else it should be an associative array with keys as object names and values as priorities to set.

integer|null $priority optional null

Integer priority to set or null for default

trigger()source public

trigger( string|CakeEvent $callback , array $params array() , array $options array() )

Trigger a callback method on every object in the collection. Used to trigger methods on objects in the collection. Will fire the methods in the order they were attached.

Options

• breakOn Set to the value or values you want the callback propagation to stop on. Can either be a scalar value, or an array of values to break on. Defaults to false.

• break Set to true to enabled breaking. When a trigger is broken, the last returned value will be returned. If used in combination with collectReturn the collected results will be returned. Defaults to false.

• collectReturn Set to true to collect the return of each object into an array. This array of return values will be returned from the trigger() call. Defaults to false.

• modParams Allows each object the callback gets called on to modify the parameters to the next object. Setting modParams to an integer value will allow you to modify the parameter with that index. Any non-null value will modify the parameter index indicated. Defaults to false.

Parameters

string|CakeEvent $callback

Method to fire on all the objects. Its assumed all the objects implement the method you are calling. If an instance of CakeEvent is provided, then then Event name will parsed to get the callback name. This is done by getting the last word after any dot in the event name (eg. Model.afterSave event will trigger the afterSave callback)

array $params optional array()

Array of parameters for the triggered callback.

array $options optional array()

Array of options.

Returns

mixed
Either the last result or all results if collectReturn is on.

Throws

CakeException
when modParams is used with an index that does not exist.
