Examples with Synthesizer javax.sound.midi.Synthesizer used on opensource projects

Example 1 with Synthesizer

use of javax.sound.midi.Synthesizer in project jdk8u_jdk by JetBrains.

the class ImplicitOpenClose method main.

public static void main(String[] args) throws Exception {
    Field f = SoftSynthesizer.class.getDeclaredField("testline");
    f.setAccessible(true);
    f.set(null, new DummySourceDataLine());
    Synthesizer synth = new SoftSynthesizer();
    ReferenceCountingDevice rcd = (ReferenceCountingDevice) synth;
    // Test single open/close cycle
    Receiver recv = rcd.getReceiverReferenceCounting();
    if (!synth.isOpen())
        throw new Exception("Synthesizer not open!");
    recv.close();
    if (synth.isOpen())
        throw new Exception("Synthesizer not closed!");
    // Test using 2 receiver cycle
    Receiver recv1 = rcd.getReceiverReferenceCounting();
    if (!synth.isOpen())
