This class encapsulates memory menagement operations, when PHP works in limited memory mode.

Constructor & Destructor Documentation

__construct

(

CacheStorage

$cache = null

)

Memory manager constructor.

$value = ''

)

Create new Zend value container, which has value always locked in memory.

Parameters

string

$value

Returns

getMemoryLimit

(

)

Get memory grow limit.

Returns

int

getMinSize

(

)

Get minimum size of values, which may be swapped.

Returns

int

load	(	Container\Movable	$container,
			$id
	)

Load value from swap file.

processUpdate	(	Container\Movable	$container,
			$id
	)

Process value update.

This method is automatically invoked by memory container only once per "modification session", but user may call memory container touch() method several times depending on used algorithm. So we have to use this check to optimize this case.

setMemoryLimit

(

$newLimit

)

Set memory grow limit.

Parameters

int

$newLimit

setMinSize

(

$newSize

)

Set minimum size of values, which may be swapped.

Parameters

int

$newSize

unlink	(	Container\Movable	$container,
			$id
	)

Unlink value container from memory manager.
