public class LabeledConstituent
extends SimpleConstituent

A LabeledConstituent object represents a single bracketing in a derivation, including start and end points and Label information, but excluding probabilistic information. It is used to represent the basic information that is accumulated in exploring parses.

Method Detail

label

public Label label()

Description copied from class: Constituent

access label

Specified by:

label in interface Labeled

Overrides:

label in class Constituent

Returns:

One of the labels of the object (if there are multiple labels, preferably the primary label, if it exists). Returns null if there is no label.

setLabel

public void setLabel(Label label)

Description copied from class: Constituent

Sets the label associated with the current Constituent, if there is one.

Specified by:

setLabel in interface Labeled

Overrides:

setLabel in class Constituent

Parameters:

label - The Label value

setFromString

public void setFromString(String labelStr)

Description copied from class: Constituent

Make a new label with this String as the "name", perhaps by doing some appropriate decoding of the string.

Specified by:

setFromString in interface Label

Overrides:

setFromString in class Constituent

Parameters:

labelStr - the String that translates into the content of the label

labelFactory

public LabelFactory labelFactory()

Return a factory for this kind of label. The factory returned is always the same one (a singleton)

Specified by:

labelFactory in interface Label

Overrides:

labelFactory in class SimpleConstituent

Returns:

the label factory

constituentFactory

public ConstituentFactory constituentFactory()

Return a factory for this kind of constituent. The factory returned is always the same one (a singleton).

Overrides:

constituentFactory in class SimpleConstituent

Returns:

The constituent factory

factory

public static ConstituentFactory factory()

Return a factory for this kind of constituent. The factory returned is always the same one (a singleton).

Returns:

The constituent factory
