Defined in: TSGraph.h

Returns the last outgoing relation for a graph element.

Prototype

relationType *GetLastOutgoingRelation(void) const;

Description

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

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