  edu.cmu.sphinx.linguist.language.grammar.GrammarArc

public class GrammarArc
extends java.lang.Object

Represents a single transition out of a grammar node. The grammar represented is a stochastic grammar, each transition has a probability associated with it. The probabilities are relative and are not necessarily constrained to total 1.0.

Note that all probabilities are maintained in the LogMath log base
