class FeatureSingleEdgeFundamentalRule(SingleEdgeFundamentalRule): (source)

Known subclasses: nltk.parse.earleychart.FeatureCompleteFundamentalRule

View In Hierarchy

A specialized version of the completer / single edge fundamental rule that operates on nonterminals whose symbols are ``FeatStructNonterminal``s. Rather than simply comparing the nonterminals for equality, they are unified.

Method _apply_complete Undocumented
Method _apply_incomplete Undocumented
Class Variable _fundamental_rule Undocumented

Inherited from SingleEdgeFundamentalRule:

Method apply Return 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.
Constant NUM_EDGES Undocumented

Inherited from AbstractChartRule (via SingleEdgeFundamentalRule, FundamentalRule):

Method __str__ Undocumented
Method apply_everywhere Return a generator that will add all edges licensed by this rule, given the edges that are currently in 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.
