__call() public method

PHP magic method, which is invoked on attempt of invocation not existing method.

It redirects method call to inner iterator.

public mixed __call ( $name, $arguments )
$name	string	Method name.
$arguments	array	Method arguments
return	mixed	Method result.

Source code

                public function __call($name, $arguments)
{
    return call_user_func_array([$this->getInnerIterator(), $name], $arguments);
}

__construct() public method

Constructor.

public void __construct ( $collection, $cursor )
$collection	yii\mongodb\file\Collection
$cursor	\MongoDB\Driver\Cursor

Source code

                public function __construct($collection, $cursor)
{
    $this->collection = $collection;
    parent::__construct($cursor);
}

__get() public method

PHP magic method, which is invoked on attempt of getting not existing property.

It returns value from the inner iterator.

public mixed __get ( $name )
$name	string	Field name.
return	mixed	Field value.

Source code

                public function __get($name)
{
    return $this->getInnerIterator()->{$name};
}

__isset() public method

PHP magic method, which is invoked on attempt of checking if a property is set.

public boolean __isset ( $name )
$name	string	Field name.
return	boolean	Whether field exists or not.

Source code

                public function __isset($name)
{
    $cursor = $this->getInnerIterator();
    return isset($cursor->$name);
}

__set() public method

PHP magic method, which is invoked on attempt of setting not existing property.

It passes value to the inner iterator.

public void __set ( $name, $value )
$name	string	Field name.
$value	mixed	Field value.

Source code

                public function __set($name, $value)
{
    $this->getInnerIterator()->{$name} = $value;
}

__unset() public method

PHP magic method, which is invoked on attempt of unsetting of property.

public void __unset ( $name )
$name	string	Field name.

Source code

                public function __unset($name)
{
    $cursor = $this->getInnerIterator();
    unset($cursor->$name);
}

count() public method

This method is required by the interface Countable.

public integer count ( )
return	integer	Elements count.

Source code

                #[\ReturnTypeWillChange]
public function count()
{
    return count($this->cursor);
}

public mixed current ( )
return	mixed	Current row

Source code

                #[\ReturnTypeWillChange]
public function current()
{
    $value = parent::current();
    if (!isset($value['file'])) {
        $value['file'] = $this->collection->createDownload(array_intersect_key($value, ['_id' => true, 'filename' => true, 'length' => true, 'chunkSize' => true]));
    }
    return $value;
}
