Detailed Description

Constructor & Destructor Documentation

__construct()

__construct	(		$value,
		Zend_Memory_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 numberr of calls necessary to modification trace

Definition at line 64 of file Value.php.

    {
        $this->_container = $container;

        $this->_value = (string)$value;

        $this->_trace = false;
    }
