Member Function Documentation

HRESULT IAAFTypeDefStrongObjRef::Initialize	(	[in, ref] aafUID_constref	id,
		[in] IAAFClassDef *	pObjType,
		[in, string] aafCharacter_constptr	pTypeName
	)

Initializes this type def to be a reference to objects of the given type, and assigns this object the given AUID.

pObjType points to the class definition of the least-derived class which is possible to be contained in property values of this type.

This method must be called after allocation, and before any other method can be called.

Succeeds if:

• Initialize() has not yet been called on this object.
• pObjType is a valid pointer.

This method will return the following codes. If more than one of the listed errors is in effect, it will return the first one encountered in the order given below:

AAFRESULT_SUCCESS

• succeeded. (This is the only code indicating success.)

AAFRESULT_ALREADY_INITIALIZED

• This object has already had Initialize() called on it.

AAFRESULT_NULL_PARAM

• either pObjType or pTypeName arg is NULL.

Parameters:

id	[in, ref] auid to be used to identify this type
pObjType	[in] class def of objects permitted to be referenced
pTypeName	[in, string] friendly name of this type definition
