public owner

@var Component|null the owner of this behavior

run()

events()

Declares event handlers for the [[owner]]'s events.

Child classes may override this method to declare what PHP callbacks should be attached to the events of the [[owner]] component.

The callbacks will be attached to the [[owner]]'s events when the behavior is attached to the owner; and they will be detached from the events when the behavior is detached from the component.

The callbacks can be any of the following:

• method in this behavior: 'handleClick', equivalent to [$this, 'handleClick']
• object method: [$object, 'handleClick']
• static method: ['Page', 'handleClick']
• anonymous function: function ($event) { ... }

The following is an example:

[
    Model::EVENT_BEFORE_VALIDATE => 'myBeforeValidate',
    Model::EVENT_AFTER_VALIDATE => 'myAfterValidate',
]

@return array events (array keys) and the corresponding event handler methods (array values).

attach()

Attaches the behavior object to the component. The default implementation will set the [[owner]] property and attach event handlers as declared in [[events]]. Make sure you call the parent implementation if you override this method.

• param Component $owner the component that this behavior is to be attached to.

detach()

Detaches the behavior object from the component. The default implementation will unset the [[owner]] property and detach event handlers declared in [[events]]. Make sure you call the parent implementation if you override this method.

className()

Returns the fully qualified name of this class. @return string the fully qualified name of this class.

__construct()

Constructor.

The default implementation does two things:

• Initializes the object with the given configuration $config.
• Call [[init()]].

If this method is overridden in a child class, it is recommended that

• the last parameter of the constructor is a configuration array, like $config here.
• call the parent implementation at the end of the constructor.

• param array $config name-value pairs that will be used to initialize the object properties

init()

Initializes the object. This method is invoked at the end of the constructor after the object is initialized with the given configuration.

__get()

Returns the value of an object property.

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $value = $object->property;.

• param string $name the property name @return mixed the property value @throws UnknownPropertyException if the property is not defined @throws InvalidCallException if the property is write-only @see __set()

__set()

Sets value of an object property.

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing $object->property = $value;.

• param string $name the property name or the event name
• param mixed $value the property value @throws UnknownPropertyException if the property is not defined @throws InvalidCallException if the property is read-only @see __get()

__isset()

Checks if a property is set, i.e. defined and not null.

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing isset($object->property).

Note that if the property is not defined, false will be returned.

• param string $name the property name or the event name @return bool whether the named property is set (not null). @see http://php.net/manual/en/function.isset.php

__unset()

Sets an object property to null.

Do not call this method directly as it is a PHP magic method that will be implicitly called when executing unset($object->property).

Note that if the property is not defined, this method will do nothing. If the property is read-only, it will throw an exception.

• param string $name the property name @throws InvalidCallException if the property is read only. @see http://php.net/manual/en/function.unset.php

__call()

Calls the named method which is not a class method.

Do not call this method directly as it is a PHP magic method that will be implicitly called when an unknown method is being invoked.

• param string $name the method name
• param array $params method parameters @throws UnknownMethodException when calling unknown method @return mixed the method return value

hasProperty()

Returns a value indicating whether a property is defined.

A property is defined if:

• the class has a getter or setter method associated with the specified name (in this case, property name is case-insensitive);
• the class has a member variable with the specified name (when $checkVars is true);

• param string $name the property name
• param bool $checkVars whether to treat member variables as properties @return bool whether the property is defined @see canGetProperty() @see canSetProperty()

canGetProperty()

Returns a value indicating whether a property can be read.

A property is readable if:

• the class has a getter method associated with the specified name (in this case, property name is case-insensitive);
• the class has a member variable with the specified name (when $checkVars is true);

• param string $name the property name
• param bool $checkVars whether to treat member variables as properties @return bool whether the property can be read @see canSetProperty()

canSetProperty()

Returns a value indicating whether a property can be set.

A property is writable if:

• the class has a setter method associated with the specified name (in this case, property name is case-insensitive);
• the class has a member variable with the specified name (when $checkVars is true);

• param string $name the property name
• param bool $checkVars whether to treat member variables as properties @return bool whether the property can be written @see canGetProperty()

hasMethod()

Returns a value indicating whether a method is defined.

The default implementation is a call to php function method_exists(). You may override this method when you implemented the php magic method __call().

• param string $name the method name @return bool whether the method is defined
