Property Details
Method Details
Defined in: yii\base\BaseObject::__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.
public mixed __call ( $name, $params ) | ||
$name | string |
The method name |
$params | array |
Method parameters |
return | mixed |
The method return value |
---|---|---|
throws | yii\base\UnknownMethodException |
when calling unknown method |
public function __call($name, $params)
{
throw new UnknownMethodException('Calling unknown method: ' . get_class($this) . "::$name()");
}
Defined in: yii\base\BaseObject::__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.
public void __construct ( $config = [] ) | ||
$config | array |
Name-value pairs that will be used to initialize the object properties |
public function __construct($config = [])
{
if (!empty($config)) {
Yii::configure($this, $config);
}
$this->init();
}
Defined in: yii\base\BaseObject::__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;
.
See also __set().
public mixed __get ( $name ) | ||
$name | string |
The property name |
return | mixed |
The property value |
---|---|---|
throws | yii\base\UnknownPropertyException |
if the property is not defined |
throws | yii\base\InvalidCallException |
if the property is write-only |
public function __get($name)
{
$getter = 'get' . $name;
if (method_exists($this, $getter)) {
return $this->$getter();
} elseif (method_exists($this, 'set' . $name)) {
throw new InvalidCallException('Getting write-only property: ' . get_class($this) . '::' . $name);
}
throw new UnknownPropertyException('Getting unknown property: ' . get_class($this) . '::' . $name);
}
Defined in: yii\base\BaseObject::__isset()
Checks if a property is set, i.e. defined and not null.
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing isset($object->property)
.
Note that if the property is not defined, false will be returned.
public boolean __isset ( $name ) | ||
$name | string |
The property name or the event name |
return | boolean |
Whether the named property is set (not null). |
---|
public function __isset($name)
{
$getter = 'get' . $name;
if (method_exists($this, $getter)) {
return $this->$getter() !== null;
}
return false;
}
Defined in: yii\base\BaseObject::__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;
.
See also __get().
public void __set ( $name, $value ) | ||
$name | string |
The property name or the event name |
$value | mixed |
The property value |
throws | yii\base\UnknownPropertyException |
if the property is not defined |
---|---|---|
throws | yii\base\InvalidCallException |
if the property is read-only |
public function __set($name, $value)
{
$setter = 'set' . $name;
if (method_exists($this, $setter)) {
$this->$setter($value);
} elseif (method_exists($this, 'get' . $name)) {
throw new InvalidCallException('Setting read-only property: ' . get_class($this) . '::' . $name);
} else {
throw new UnknownPropertyException('Setting unknown property: ' . get_class($this) . '::' . $name);
}
}
Defined in: yii\base\BaseObject::__unset()
Sets an object property to null.
Do not call this method directly as it is a PHP magic method that
will be implicitly called when executing unset($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.
public void __unset ( $name ) | ||
$name | string |
The property name |
throws | yii\base\InvalidCallException |
if the property is read only. |
---|
public function __unset($name)
{
$setter = 'set' . $name;
if (method_exists($this, $setter)) {
$this->$setter(null);
} elseif (method_exists($this, 'get' . $name)) {
throw new InvalidCallException('Unsetting read-only property: ' . get_class($this) . '::' . $name);
}
}
Defined in: yii\base\BaseObject::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);
See also canSetProperty().
public boolean canGetProperty ( $name, $checkVars = true ) | ||
$name | string |
The property name |
$checkVars | boolean |
Whether to treat member variables as properties |
return | boolean |
Whether the property can be read |
---|
public function canGetProperty($name, $checkVars = true)
{
return method_exists($this, 'get' . $name) || $checkVars && property_exists($this, $name);
}
Defined in: yii\base\BaseObject::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);
See also canGetProperty().
public boolean canSetProperty ( $name, $checkVars = true ) | ||
$name | string |
The property name |
$checkVars | boolean |
Whether to treat member variables as properties |
return | boolean |
Whether the property can be written |
---|
public function canSetProperty($name, $checkVars = true)
{
return method_exists($this, 'set' . $name) || $checkVars && property_exists($this, $name);
}
::class
instead.
Defined in: yii\base\BaseObject::className()
Returns the fully qualified name of this class.
public static string className ( ) | ||
return | string |
The fully qualified name of this class. |
---|
public static function className()
{
return get_called_class();
}
Callculate to number of items when using count() function against the QueryIterator object.
public integer count ( ) | ||
return | integer |
The number of elements in the object. |
---|
#[\ReturnTypeWillChange]
public function count()
{
return count($this->data);
}
Defined in: yii\base\BaseObject::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()
.
public boolean hasMethod ( $name ) | ||
$name | string |
The method name |
return | boolean |
Whether the method is defined |
---|
public function hasMethod($name)
{
return method_exists($this, $name);
}
Defined in: yii\base\BaseObject::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);
See also:
public boolean hasProperty ( $name, $checkVars = true ) | ||
$name | string |
The property name |
$checkVars | boolean |
Whether to treat member variables as properties |
return | boolean |
Whether the property is defined |
---|
public function hasProperty($name, $checkVars = true)
{
return $this->canGetProperty($name, $checkVars) || $this->canSetProperty($name, false);
}
Defined in: yii\base\BaseObject::init()
Initializes the object.
This method is invoked at the end of the constructor after the object is initialized with the given configuration.
public void init ( ) |
public function init()
{
}
Iterator get current key.
public string key ( ) | ||
return | string |
The current key |
---|
#[\ReturnTypeWillChange]

{
return next($this->data);
}
Iterator rewind.
public array rewind ( ) |
#[\ReturnTypeWillChange]
