    public
                    __call(string $name, array<string|int, mixed> $params) : mixed

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.

Parameters

$name : string: the method name
$params : array<string|int, mixed>: method parameters

Return values

mixed —

the method return value

__clone()

This method is called after the object is created by cloning an existing one.


    public
                    __clone() : mixed

It removes all behaviors because they are attached to the old object.

__construct()

Constructor.


    public
                    __construct([array<string|int, mixed> $config = [] ]) : mixed

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.

Parameters

$config : array<string|int, mixed> = []: name-value pairs that will be used to initialize the object properties

__get()

Returns the value of a component property.


    public
                    __get(string $name) : mixed

This method will check in the following order and act accordingly:

a property defined by a getter: return the getter result
a property of a behavior: return the behavior property value

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

Parameters

$name : string: the property name

Return values

mixed —

the property value or the value of a behavior's property

__isset()

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


    public
                    __isset(string $name) : bool

This method will check in the following order and act accordingly:

a property defined by a setter: return whether the property is set
a property of a behavior: return whether the property is set
return false for non existing properties

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

Parameters

$name : string: the property name or the event name

Return values

bool —

whether the named property is set

__set()

Sets the value of a component property.


    public
                    __set(string $name, mixed $value) : mixed

This method will check in the following order and act accordingly:

a property defined by a setter: set the property value
an event in the format of "on xyz": attach the handler to the event "xyz"
a behavior in the format of "as xyz": attach the behavior named as "xyz"
a property of a behavior: set the behavior property value

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

Parameters

$name : string: the property name or the event name
$value : mixed: the property value

__unset()

Sets a component property to be null.


    public
                    __unset(string $name) : mixed

This method will check in the following order and act accordingly:

a property defined by a setter: set the property value to be null
a property of a behavior: set the property value to be null

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

Parameters

$name : string: the property name

    public
                    afterSend(MessageInterface $message, bool $isSuccessful) : mixed

Parameters

$message : MessageInterface
$isSuccessful : bool

attachBehavior()

Attaches a behavior to this component.


    public
                    attachBehavior(string $name, string|array<string|int, mixed>|Behavior $behavior) : Behavior

This method will create the behavior object based on the given configuration. After that, the behavior object will be attached to this component by calling the [[Behavior::attach()]] method.

Parameters

$name : string

the name of the behavior.

$behavior : string|array<string|int, mixed>|Behavior

the behavior configuration. This can be one of the following:

a [[Behavior]] object
a string specifying the behavior class
an object configuration array that will be passed to [[Yii::createObject()]] to create the behavior object.

Return values

Behavior —

the behavior object

Attaches a list of behaviors to the component.


    public
                    attachBehaviors(array<string|int, mixed> $behaviors) : mixed

Each behavior is indexed by its name and should be a [[Behavior]] object, a string specifying the behavior class, or an configuration array for creating the behavior.

beforeSend()

This method is invoked right before mail send.


    public
                    beforeSend(MessageInterface $message) : bool

You may override this method to do last-minute preparation for the message. If you override this method, please make sure you call the parent implementation first.

Parameters

$message : MessageInterface

Return values

bool —

whether to continue sending an email.

behaviors()

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


    public
                    behaviors() : array<string|int, mixed>

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 [[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).

Return values

array<string|int, mixed> —

the behavior configurations.

                    canSetProperty(string $name[, bool $checkVars = true ][, bool $checkBehaviors = true ]) : bool

A property can be written if:

the class has a setter method associated with the specified name (in this case, property name is case-insensitive);

null, meaning the message instance will be returned without body content.

The view to be rendered can be specified in one of the following formats:

path alias (e.g. "@app/mail/contact");
a relative view name (e.g. "contact") located under [[viewPath]].

});

Sends the given email message.


    public
                    send(MessageInterface $message) : bool

This method will log a message about the email being sent. If [[useFileTransport]] is true, it will save the email as a file under [[fileTransportPath]]. Otherwise, it will call [[sendMessage()]] to send the email to its recipient(s). Child classes should implement [[sendMessage()]] with the actual email sending logic.

Parameters

$message : MessageInterface: email message instance to be sent

Return values

bool —

whether the message has been sent successfully

sendMultiple()

Sends multiple messages at once.


    public
                    sendMultiple(array<string|int, mixed> $messages) : int

The default implementation simply calls [[send()]] multiple times. Child classes may override this method to implement more efficient way of sending multiple messages.

Return values

int —

number of messages that are successfully sent.
