public class MixerLine

extends java.io.InputStream

MixerLine is a simple G711 mixer with N input lines (InputStream) and one output line (the MixerLine itself).

Each input line has an identifier (Object) used as key when adding or removing the line.

Constructor Summary

MixerLine(java.lang.Object mixer_id)
Creates a new MixerLine.

MixerLine(java.lang.Object mixer_id, java.util.Hashtable input_lines)
Creates a new MixerLine.

Method Summary

void	addLine(java.lang.Object id, java.io.InputStream is) Adds a new line.
int	available() Returns the number of bytes that can be read (or skipped over) from this input stream without blocking by the next caller of a method for this input stream.
void	close() Closes this input stream and releases any system resources associated with the stream.
void	mark(int readlimit) Marks the current position in this input stream.
boolean	markSupported() Tests if this input stream supports the mark and reset methods.
int	read() Reads the next byte of data from the input stream.
int	read(byte[] b) Reads some number of bytes from the input stream and stores them into the buffer array b.
int	read(byte[] b, int off, int len) Reads up to len bytes of data from the input stream into an array of bytes.
void	removeLine(java.lang.Object id) Removes a line.
void	reset() Repositions this stream to the position at the time the mark method was last called on this input stream.
long	skip(long n) Skips over and discards n bytes of data from this input stream.
