  net.sf.statcvs.model.Directory

All Implemented Interfaces:

java.lang.Comparable

public abstract class Directory

extends java.lang.Object

implements java.lang.Comparable

Represents a directory in the Repository, a container for VersionedFiles and subDirectorys. A new root directory is created by createRoot(). The createSubdirectory(java.lang.String) method creates new subdirectories. TODO: Rename getCurrentLOC to getCurrentLines or getCurrentLineCount
