Class UnnamedDependency

java.lang.Object

edu.stanford.nlp.trees.UnnamedDependency

All Implemented Interfaces:

Dependency<Label,Label,java.lang.Object>, java.io.Serializable

Direct Known Subclasses:

NamedDependency, UnnamedConcreteDependency

public class UnnamedDependency
extends java.lang.Object
implements Dependency<Label,Label,java.lang.Object>

An individual dependency between a head and a dependent. The head and dependent are represented as a Label. For example, these can be a Word or a WordTag. If one wishes the dependencies to preserve positions in a sentence, then each can be a LabeledConstituent.

Method Detail

governor

public Label governor()

Description copied from interface: Dependency

Describes the governor (regent/head) of the dependency relation.

Specified by:

governor in interface Dependency<Label,Label,java.lang.Object>

Returns:

The governor of this dependency

dependent

public Label dependent()

Description copied from interface: Dependency

Describes the dependent (argument/modifier) of the dependency relation.

Specified by:

dependent in interface Dependency<Label,Label,java.lang.Object>

Returns:

the dependent of this dependency

name

public java.lang.Object name()

Description copied from interface: Dependency

Names the type of dependency (subject, instrument, ...). This might be a String in the simplest case, but can provide for arbitrary object types.

Specified by:

name in interface Dependency<Label,Label,java.lang.Object>

Returns:

the name for this dependency type

getText

protected java.lang.String getText(Label label)

hashCode

public int hashCode()

Overrides:

hashCode in class java.lang.Object

equals

public boolean equals(java.lang.Object o)

Overrides:

equals in class java.lang.Object

equalsIgnoreName

public boolean equalsIgnoreName(java.lang.Object o)

Description copied from interface: Dependency

Are two dependencies equal if you ignore the dependency name.

Specified by:

equalsIgnoreName in interface Dependency<Label,Label,java.lang.Object>

Parameters:

o - The thing to compare against ignoring name

Returns:

true iff the head and dependent are the same.

toString

public java.lang.String toString()

Overrides:

toString in class java.lang.Object

toString

public java.lang.String toString(java.lang.String format)

Provide different printing options via a String keyword. The recognized options are currently "xml", and "predicate". Otherwise the default toString() is used.

Specified by:

toString in interface Dependency<Label,Label,java.lang.Object>

Parameters:

format - A format string, either "xml" or you get the default

Returns:

A String representation of the dependency

dependencyFactory

public DependencyFactory dependencyFactory()

Description copied from interface: Dependency

Provide a factory for this kind of dependency

Specified by:

dependencyFactory in interface Dependency<Label,Label,java.lang.Object>

Returns:

A DependencyFactory

factory

public static DependencyFactory factory()
