      edu.rice.cs.util.NullFile

All Implemented Interfaces:

Serializable, Comparable<File>

public class NullFile
extends File
implements Serializable

A null file. This class is NOT a singleton because we need multiple, distinct null files for untitled documents. The equals method is overridden so that distinct NullFile objects (which all have the same path) are unequal.
