Detailed Description

Class: CIccXformCreator.

Purpose: CIccXformCreator uses a singleton pattern to provide dynamically upgradeable CIccXform derived object creation based on xform type.

CreateXform()

static CIccXform * CIccXformCreator::CreateXform ( icXformType xformType, CIccTag * pTag = NULL, CIccCreateXformHintManager * pHintManager = NULL )

inlinestatic

Function: CreateXform(xformTypeSig) Create a xform of type xformTypeSig.

Parameter(s): xformType = signature of the ICC xform type for the xform to be created pTag = tag information for created xform pHintManager = contains additional information used to create xform

Returns a new CIccXform object of the given xform type. Each factory in the factoryStack is used until a factory supports the signature type.

GetInstance()

CIccXformCreator * CIccXformCreator::GetInstance ( )

staticprivate

Function: GetInstance() Private static function to access singleton CiccXformCreator Object.

Parameter(s): None

Returns the singleton CIccXformCreator object. It will allocate a new one and push a single CIccSpecXform Factory object onto the factory stack if the singleton has not been intialized.

Definition at line 130 of file IccXformFactory.cpp.

{

PopFactory()

static IIccXformFactory * CIccXformCreator::PopFactory ( )

inlinestatic

Function: PopFactory() Remove the top IIccXformFactory from the stack of xform factories tracked by the system.

Parameter(s): None

Returns the top IIccXformFactory from the stack of xform factories tracked by the system. The returned xform factory is no longer owned by the system and needs to be deleted to avoid memory leaks.

Note: The initial CIccSpecXformFactory cannot be popped off the stack.

Here is the call graph for this function:

PushFactory()

static void CIccXformCreator::PushFactory ( IIccXformFactory * pFactory )

inlinestatic

Function: PushFactory(pFactory) Add an IIccXformFactory to the stack of xform factories tracked by the system.

Parameter(s): pFactory = pointer to an IIccXformFactory object to add to the system. The pFactory must be created with new, and will be owned CIccXformCreator until popped off the stack using PopFactory(). Any factories not popped off will be taken care of properly on application shutdown.
