Instance Methods

iter of EdgeI

apply_iter(self, chart, grammar, edge1)
Returns: A generator that will add edges licensed by this rule and the given edges to the chart, one at a time.

int NUM_EDGES = 1
The number of existing edges that this rule uses to license new edges.

Method Details

apply_iter(self, chart, grammar, edge1)

source code

Parameters:

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.
