Detailed Description

String value object.

It's an OO string wrapper. Used to intercept string updates.

Constructor & Destructor Documentation

__construct	(		$value,
		Container\Movable	$container
	)

Object constructor.

Parameters

string	$value
\Zend\Memory\Container\Movable	$container

Object is marked as just modified by memory manager So we don't need to trace followed object modifications and object is processed (and marked as traced) when another memory object is modified.

It reduces overall number of calls necessary to modification trace
