drain
public void drain()
This method blocks until whatever data is buffered in the
DataLine's internal buffer has been drained.
- drain in interface DataLine
flush
public void flush()
This flushes the DataLine by discarding any buffered data.
- flush in interface DataLine
isActive
public boolean isActive()
Return true if this line is active, meaning that it is actively
performing audio I/O.
- isActive in interface DataLine
isRunning
public boolean isRunning()
Return true if this line is running, meaning that it has been
started. When the line is stopped, this method will return false.
- isRunning in interface DataLine
start
public void start()
Start processing data. This will emit a START event.
- start in interface DataLine
stop
public void stop()
Stop processing data. This will emit a STOP event.
- stop in interface DataLine
write
public int write(byte[] buf,
int offset,
int length) Write audio data to this line. The data must be an integral number
of frames, as determined by the audio format.
- write in interface SourceDataLine
buf - a byte array of audio dataoffset - index of the first byte in the array to uselength - the number of bytes to write
- the number of bytes written
