Constructor Detail

AlsaMidiIn

public AlsaMidiIn(AlsaSeq alsaSeq,
                  int nDestPort,
                  int nSourceClient,
                  int nSourcePort,
                  AlsaMidiIn.AlsaMidiInListener listener)

Receives events without timestamping them. Does establish a subscription where events are routed directely (not getting a timestamp).

Parameters:

alsaSeq - The client that should be used to receive events.

nDestPort - The port number that should be used to receive events. This port has to exist on the client represented by alsaSeq.

nSourceClient - The client number that should be listened to. This and nSourcePort must exist prior to calling this constructor. The port has to allow read subscriptions.

nSourcePort - The port number that should be listened to. This and nSourceClient must exist prior to calling this constructor. The port has to allow read subscriptions.

listener - The listener that should receive the MidiMessage objects created here from received events.

AlsaMidiIn

                  int nDestPort,
                  int nSourceClient,
                  int nSourcePort,
                  int nTimestampingQueue,
                  boolean bRealtime,
                  AlsaMidiIn.AlsaMidiInListener listener)

Does establish a subscription where events are routed through a queue to get a timestamp.

Method Detail

run

public void run()

The working part of the class. Here, the thread repeats in blocking in a call to getEvent() and calling the listener's dequeueEvent() method.

Specified by:

run in interface Runnable

Overrides:
