Interface Receiver

All Superinterfaces:

AutoCloseable

All Known Subinterfaces:

MidiDeviceReceiver

public interface Receiver
extends AutoCloseable

A Receiver receives MidiEvent objects and typically does something useful in response, such as interpreting them to generate sound or raw MIDI output. Common MIDI receivers include synthesizers and MIDI Out ports.

Method Summary

Modifier and Type	Method	Description
void	close()	Indicates that the application has finished using the receiver, and that limited resources it requires may be released or made available.
void	send(MidiMessage message, long timeStamp)	Sends a MIDI message and time-stamp to this receiver.

Method Details

send

void send(MidiMessage message,
 long timeStamp)

Sends a MIDI message and time-stamp to this receiver. If time-stamping is not supported by this receiver, the time-stamp value should be -1.

Parameters:

message - the MIDI message to send

timeStamp - the time-stamp for the message, in microseconds

Throws:

IllegalStateException - if the receiver is closed

close

void close()

Indicates that the application has finished using the receiver, and that limited resources it requires may be released or made available.

If the creation of this Receiver resulted in implicitly opening the underlying device, the device is implicitly closed by this method. This is true unless the device is kept open by other Receiver or Transmitter instances that opened the device implicitly, and unless the device has been opened explicitly. If the device this Receiver is retrieved from is closed explicitly by calling MidiDevice.close, the Receiver is closed, too. For a detailed description of open/close behaviour see the class description of MidiDevice.
