All Classes | Methods

Implemented by	yii\test\ActiveFixture, yii\test\ArrayFixture, yii\test\BaseActiveFixture
Available since version	2.0
Source Code	https://github.com/yiisoft/yii2/blob/master/framework/base/ArrayAccessTrait.php

ArrayAccessTrait provides the implementation for IteratorAggregate, ArrayAccess and Countable.

Note that ArrayAccessTrait requires the class using it contain a property named data which should be an array. The data will be exposed by ArrayAccessTrait to support accessing the class object like an array.

Method Details

count() public method

Returns the number of data items.

This method is required by Countable interface.

public integer count ( )
return	integer	Number of data elements.

getIterator() public method

Returns an iterator for traversing the data.

This method is required by the SPL interface IteratorAggregate. It will be implicitly called when you use foreach to traverse the collection.

public ArrayIterator getIterator ( )
return	ArrayIterator	An iterator for traversing the cookies in the collection.

offsetExists() public method

This method is required by the interface ArrayAccess.

public boolean offsetExists ( $offset )
$offset	mixed	The offset to check on

offsetGet() public method

This method is required by the interface ArrayAccess.

public mixed offsetGet ( $offset )
$offset	integer	The offset to retrieve element.
return	mixed	The element at the offset, null if no element is found at the offset

offsetSet() public method

This method is required by the interface ArrayAccess.

public void offsetSet ( $offset, $item )
$offset	integer	The offset to set element
$item	mixed	The element value

offsetUnset() public method

This method is required by the interface ArrayAccess.

public void offsetUnset ( $offset )
$offset	mixed	The offset to unset element
