Defined in: TSGraph.h

Returns the first outgoing relation for a graph element.

Prototype

relationType *GetFirstOutgoingRelation(void) const;

Description

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