Class SimpleConstituent

java.lang.Object
  edu.stanford.nlp.trees.Constituent
      edu.stanford.nlp.trees.SimpleConstituent

All Implemented Interfaces:

Label, Labeled, Scored

Direct Known Subclasses:

LabeledConstituent

public class SimpleConstituent
extends Constituent

A SimpleConstituent object defines a generic edge in a graph. The SimpleConstituent records only the endpoints of the Constituent, as two integers. It doesn't label the edges. (It doesn't implement equals() since this actually decreases performance on a non-final class (requires dynamic resolution of which to call).)
