      com.partnersoft.io.vfs.VfsRandomAccessInputStream

All Implemented Interfaces:

java.io.Closeable

public class VfsRandomAccessInputStream
extends java.io.InputStream

A wrapper implementation of InputStream that forwards all I/O to an enclosed VfsRandomAccess object. Useful for VfsImplementations where there are no existing InputStream implementations and you just want to implement the VfsRandomAccess and get on with life.
