__call()

Calls the named method which is not a class method.

This method will check if any attached behavior has the named method and will execute it if available.

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.

View source

Arguments

• $name (string) – The method name
• $params (array) – Method parameters

Returns

mixed – The method return value

Throws

• yii\base\UnknownMethodException
  when calling unknown method

__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.

View source

Arguments

• $config (array) – Name-value pairs that will be used to initialize the object properties

addresses()

Returns a new address query.

View source

Arguments

• $criteria (array)

Returns

craft\elements\db\AddressQuery

assets()

Returns a new asset query.

View source

Arguments

• $criteria (array)

Returns

craft\elements\db\AssetQuery

behaviors()

Returns a list of behaviors that this component should behave as.

Child classes may override this method to specify the behaviors they want to behave as.

The return value of this method should be an array of behavior objects or configurations indexed by behavior names. A behavior configuration can be either a string specifying the behavior class or an array of the following structure:

'behaviorName' => [
    'class' => 'BehaviorClass',
    'property1' => 'value1',
    'property2' => 'value2',
]

Note that a behavior class must extend from \craft\web\twig\variables\Behavior. Behaviors can be attached using a name or anonymously. When a name is used as the array key, using this name, the behavior can later be retrieved using getBehavior() or be detached using detachBehavior(). Anonymous behaviors can not be retrieved or detached.

Behaviors declared in this method will be attached to the component automatically (on demand).

View source

Returns

array – The behavior configurations.

canGetProperty()

Returns a value indicating whether a property can be read.

A property can be read 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);
• an attached behavior has a readable property of the given name (when $checkBehaviors is true).

View source

Arguments

• $name (string) – The property name
• $checkVars (boolean) – Whether to treat member variables as properties
• $checkBehaviors (boolean) – Whether to treat behaviors' properties as properties of this component

Returns

boolean – Whether the property can be read
