IEDLClassFactory Class Reference

EDL Factory Interface allows one part of the EDL infrastructure to register class creation methods identified by either GUIDs and /or names (strings) and then another part of the EDL infrastructure to request the creation of instances of one or more of these classes by quoting the same GUID or name.

EDL Class Factory

Member Function Documentation

createInstance()

virtual IEDLObjectPtr IEDLClassFactory::createInstance ( const CClassID & id, CClassParams * pParams = NULL )

pure virtual

Creates the registered class by CClassID.

Parameters

id	Class GUID
pParams	Parameters for class initialization

Returns

IEDLObjectPtr A smart pointer to EDLObject interface to newly created class

createInstanceJawsMako()

virtual IEDLObjectPtr IEDLClassFactory::createInstanceJawsMako ( const CClassID & id, CClassParams * pParams = NULL, IEDLClassFactory * factory = NULL )

pure virtual

Creates the registered class by CClassID.

Parameters

id	Class GUID
pParams	Parameters for class initialization
factory	IEDLClassFactory Pointer to JawsMako

Returns

IEDLObjectPtr A smart pointer to EDLObject interface to newly created class

findNamedClass()

virtual bool IEDLClassFactory::findNamedClass ( const EDLSysString & strName, CClassID & id )

pure virtual

Retrieve GUID registered under the string name.

Parameters

strName	Name to find
id	Placeholder for result

Returns

bool True on success

getSingleton()

virtual IEDLObjectPtr IEDLClassFactory::getSingleton ( const CClassID & id )

pure virtual

Creates the EDL singleton (for example FontLibrary or ColorManager)

Parameters

id	Class GUID

Returns

IEDLObjectPtr A smart pointer to the IEDLObject

registerClass()

virtual bool IEDLClassFactory::registerClass ( const CClassID & id, creatorFunc f )

pure virtual

Register a GUID with creator function.

Parameters

id	Class GUID
f	Function that creates the class

Returns

bool True on success

registerNamedClass()

virtual bool IEDLClassFactory::registerNamedClass ( const EDLSysString & strName, const CClassID & id, bool overwrite = true )

pure virtual

Register a GUID under a string name.

Parameters

strName	Name for registartion
id	Class GUID
overwrite	If overwrite is true then overwites old name registration else returns false

Returns

bool True on success
