Module: Jumoku::Strategies::EdgeLabelingBackend

Included in:
SimpleEdgeLabeling
Defined in:
lib/jumoku/strategies/edge_labeling.rb

Overview

Edge labeling strategies are concerned with the way edges or arcs are labeled. Simple labeling schemes are based on indexing with increasing integers, whereas some other strategies elaborate on notions such as weight or symetry.

This module provides basic implementation for the common ground used by custom strategies.
