Method Summary

boolean	exists(java.lang.String path) True if the file exists.
java.io.InputStream	inputStreamFor(java.lang.String path) This is weird - we want an unprocessed copy of the file, not processed, so we have to run around to prevent e.g.
boolean	isDirectory(java.lang.String path) True if the path is a directory.
boolean	isWritable() True if this module supports writing.
long	lastModified(java.lang.String path) This is currently a nonfunctional stub that always returns zero.
VFSNode[]	list(java.lang.String path) Lists the entries in the virtual directory at path.
java.io.OutputStream	outputStreamFor(java.lang.String path) Returns on output stream for the given path.
VFSRandomAccess	randomAccessFor(java.lang.String path) Returns a random-access handle for the given path.
void	remove(java.lang.String path) Removes the file at the given path.
int	sizeOf(java.lang.String path) Returns the file size for the given path.
java.lang.String	toString()
