Prototype

relationType *GetLastIncomingRelation(void) const;

Description

The GetLastIncomingRelation function returns the last incoming relation for a graph element. If there are no incoming relations, then the return value is nullptr.

To iterate through all incoming relations for a graph element, first call the GraphElement::GetLastIncomingRelation function, and then call the GraphRelation::GetPreviousIncomingRelation function iteratively for the returned relations until nullptr is returned.
