Method name. |
| $arguments | array |
Method arguments |
| return | mixed |
Method result. |
|---|---|---|
public function __call($name, $arguments)
{
return call_user_func_array([$this->getInnerIterator(), $name], $arguments);
}
Constructor.
| public void __construct ( $collection, $cursor ) | ||
| $collection | yii\mongodb\file\Collection | |
| $cursor | \MongoDB\Driver\Cursor | |
public function __construct($collection, $cursor)
{
$this->collection = $collection;
parent::__construct($cursor);
}
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 |

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

| public boolean __isset ( $name ) | ||
| $name | string |
Field name. |
| return | boolean |
Whether field exists or not. |
|---|---|---|
public function __isset($name)
{
$cursor = $this->getInnerIterator();
return isset($cursor->$name);
}
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. |
| $value | mixed |
Field value. |
public function __set($name, $value)
{
$this->getInnerIterator()->{$name} = $value;
}
PHP magic method, which is invoked on attempt of unsetting of property.
| public void __unset ( $name ) | ||
| $name | string |
Field name. |
public function __unset($name)
{
$cursor = $this->getInnerIterator();
unset($cursor->$name);
}

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

#[\ReturnTypeWillChange]
public function current()
{
$value = parent::current();
if (!isset($value['file'])) {

}
return $value;
}
