A read-only enumerator of IOpcRelationship interface pointers.

Inheritance

The IOpcRelationshipEnumerator interface inherits from the IUnknown interface. IOpcRelationshipEnumerator also has these types of members:

Methods

The IOpcRelationshipEnumerator interface has these methods.


IOpcRelationshipEnumerator::Clone Creates a copy of the current enumerator and all its descendants. (IOpcRelationshipEnumerator.Clone)
IOpcRelationshipEnumerator::GetCurrent Gets the IOpcRelationship interface pointer at the current position of the enumerator.
IOpcRelationshipEnumerator::MoveNext Moves the current position of the enumerator to the next IOpcRelationship interface pointer.
IOpcRelationshipEnumerator::MovePrevious Moves the current position of the enumerator to the previous IOpcRelationship interface pointer.

Remarks

To get a pointer to this interface, call either the IOpcRelationshipSet::GetEnumerator or the IOpcRelationshipSet::GetEnumeratorForType method.

When an enumerator is created, the current position precedes the first pointer. To set the current position to the first pointer of the enumerator, call the MoveNext method after creating the enumerator.

Note Changes to the set will invalidate the enumerator, and all subsequent calls will fail.
