 HighlightedEdges
 retrieve the highlighted edges from a graph

 Calling Sequence HighlightedEdges( G )

Parameters

 G - graph

Description

 • The HighlightedEdges command returns a set (which may be empty) of the edges of a graph G that have been highlighted.
 • An edge is considered to have been highlighted if it is to be drawn with a color other than the default.
