(

$backend = null

Member Function Documentation

create

(

$value = ''

)

Create new Zend_Memory value container.

Parameters

string

$value

Returns

Zend_Memory_Container_Interface

Exceptions

Zend_Memory_Exception

createLocked

(

$value = ''

)

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

Parameters

string

$value

Returns

Zend_Memory_Container_Interface

Exceptions

Zend_Memory_Exception

getMemoryLimit

(

)

Get memory grow limit.

Returns

integer

getMinSize

(

)

Get minimum size of values, which may be swapped.

Returns

integer

load	(	Zend_Memory_Container_Movable	$container,
			$id
	)

Load value from swap file.

processUpdate	(	Zend_Memory_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

integer

$newLimit

Exceptions

Zend_Exception

setMinSize

(

$newSize

)

Set minimum size of values, which may be swapped.

Parameters

integer

$newSize

unlink	(	Zend_Memory_Container_Movable	$container,
			$id
	)

Unlink value container from memory manager.
