Field Summary

private java.nio.ByteBuffer[]	buffers The buffers (one for each channel) into which the audio data will be rendered
private int	channels The number of channels in the file
private int	currentSlice The number of frames rendered so far.
private REXHandle	handle The REX handle representing the file to be streamed
private int	length The length of the file in sample frames
private int	sliceCount The number of slices
private REXSliceInfo[]	sliceInfos The REXSliceInfo objects for all slices

Constructor Summary

REXInputStream(REXHandle handle)
Constrcuts a new REXInputStream

Method Summary

int	available()
boolean	markSupported()
int	read() because of the frame size granularity of 4 or 8 bytes, this method should never be called.
int	read(byte[] b)
int	read(byte[] b, int off, int len)
private boolean	renderNext() Render the next part of audio data
long	skip(long s)
