IOpcRelationshipSelectorEnumerator interface (msopc.h)
A read-only enumerator of IOpcRelationshipSelector interface pointers.
Inheritance
The IOpcRelationshipSelectorEnumerator interface inherits from the IUnknown interface. IOpcRelationshipSelectorEnumerator also has these types of members:
Methods
The IOpcRelationshipSelectorEnumerator interface has these methods.
| IOpcRelationshipSelectorEnumerator::Clone Creates a copy of the current IOpcRelationshipSelectorEnumeratorinterface pointer and all its descendants. |
| IOpcRelationshipSelectorEnumerator::GetCurrent Gets the IOpcRelationshipSelector interface pointer at the current position of the enumerator. |
| IOpcRelationshipSelectorEnumerator::MoveNext Moves the current position of the enumerator to the next IOpcRelationshipSelectorinterface pointer. |
| IOpcRelationshipSelectorEnumerator::MovePrevious Moves the current position of the enumerator to the previous IOpcRelationshipSelectorinterface pointer. |
Remarks
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.
Changes to the set will invalidate the enumerator, and all subsequent calls to it will fail.
To get an IOpcRelationshipSelectorEnumerator interface pointer, call the IOpcRelationshipSelectorSet::GetEnumerator or IOpcSignatureRelationshipReference::GetRelationshipSelectorEnumerator method.
