Class WeakRefFilesCache

java.lang.Object
  org.apache.commons.vfs2.provider.AbstractVfsComponent
      org.apache.commons.vfs2.cache.AbstractFilesCache
          org.apache.commons.vfs2.cache.SoftRefFilesCache
              org.apache.commons.vfs2.cache.WeakRefFilesCache

All Implemented Interfaces:

FilesCache, VfsComponent

public class WeakRefFilesCache
extends SoftRefFilesCache

This implementation caches every file as long as it is strongly reachable by the java vm. As soon as the object is no longer reachable it will be discarded. In contrast to the SoftRefFilesCache this implementation might free resources faster as it don't wait until a memory limitation.
