ITcVnForwardIterator

Inheritance Hierarchy

Name	Origin	Description
TcAddRef	ITcUnknown	Increments the reference counter.
TcQueryInterface	ITcUnknown	Get a reference to an implemented interface.
TcRelease	ITcUnknown	Decrements the reference counter.
CheckIfBegin	ITcVnIteratorBase	Checks if the iterator points to the first element.
CheckIfEnd	ITcVnIteratorBase	Checks if the iterator points to the past-the-end element (alternatively use F_VN_CheckIfIteratorIsAtEnd).
GetValueSize	ITcVnIteratorBase	Gets the memory size (in byte) required by the value the iterator points to.
GetValueTypeGuid	ITcVnIteratorBase	Gets the type GUID of the value the iterator points to.
SetToBegin	ITcVnIteratorBase	Sets the iterator to the first element (alternatively use F_VN_SetIteratorToBegin).
SetToEnd	ITcVnIteratorBase	Sets the iterator to the past-the-end element.
CheckIfEqualTo	ITcVnForwardIterator	Checks if iterator is equal to another iterator.
GetContainer	ITcVnForwardIterator	Gets a pointer to the current element converted into an ITcVnContainer interface and increment its reference counter (only possible for container types). (Alternatively use F_VN_GetContainer.)
Increment	ITcVnForwardIterator	Increments the iterator. (Alternatively use F_VN_IncrementIterator.)
SetContainer	ITcVnForwardIterator	Sets the current element using an ITcVnContainer interface (only possible for container types). (Alternatively use F_VN_SetContainer.)
