Opens the line with the specified format and suggested buffer size, causing the line to acquire any required system resources and become operational.

Usage

From source file:SoundManagerTest.java

/**
 * Signals that a PooledThread has started. Creates the Thread's line and
 * buffer.//from  w  ww . j a  v  a 2s.  c  o m
 */
protected void threadStarted() {
    // wait for the SoundManager constructor to finish
    synchronized (this) {
        try {
            wait();
        } catch (InterruptedException ex) {
        }
    }

    // use a short, 100ms (1/10th sec) buffer for filters that
    // change in real-time
    int bufferSize = playbackFormat.getFrameSize() * Math.round(playbackFormat.getSampleRate() / 10);

    // create, open, and start the line
    SourceDataLine line;
    DataLine.Info lineInfo = new DataLine.Info(SourceDataLine.class, playbackFormat);
    try {

    } catch (LineUnavailableException ex) {
        // the line is unavailable - signal to end this thread
        Thread.currentThread().interrupt();
        return;
    }

    line.start();

    // create the buffer
    byte[] buffer = new byte[bufferSize];

    // set this thread's locals
    localLine.set(line);
