net.shredzone.ifish.ltr
Class OggFastFileStream

java.lang.Object
  net.shredzone.ifish.ltr.OggFastFileStream

All Implemented Interfaces:

PhysicalOggStream

---

public class OggFastFileStream
extends Object
implements PhysicalOggStream

Replacement file reader class. The original J-Ogg FileStream has the major disadvantage that it reads the entire file, even though we just need a few byte from it. This FastFileStream will only read as little information as possible.
