Defined in: TSGraph.h

Returns the first incoming relation for a graph element.

Prototype

relationType *GetFirstIncomingRelation(void) const;

Description

The GetFirstIncomingRelation function returns the first 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::GetFirstIncomingRelation function, and then call the GraphRelation::GetNextIncomingRelation function iteratively for the returned relations until nullptr is returned.
