GraphEdge::GetNextOutgoingEdge

Defined in: C4Graph.h

Returns the next outgoing edge for a graph element.

Prototype

edgeType *GetNextOutgoingEdge(void) const;

Description

The GetNextOutgoingEdge function returns the next outgoing edge for the graph element at which the edge for which the function is called starts. If there is no next outgoing edge, then the return value is nullptr.

To iterate through all outgoing edges for a graph element using this function, first call the GraphElement::GetFirstOutgoingEdge function for the graph element, and then call the GetNextOutgoingEdge function iteratively for the returned edges until nullptr is returned.
