  • edges - A set of existing edges. The number of edges that should be passed to apply is specified by the NUM_EDGES class variable.
Returns: iter of EdgeI
A generator that will add edges licensed by this rule and the given edges to the chart, one at a time. Each time the generator is resumed, it will either add a new edge and yield that edge; or return.
