## javax.sound.midi
Interface Transmitter

    public interface Transmitter

A `Transmitter` sends ``MidiEvent`` objects to one or more ``Receivers``. Common MIDI transmitters include sequencers and MIDI input ports.

See Also:
  `Receiver`

Method Summary
`void` | `close()` Indicates that the application has finished using the transmitter, and that limited resources it requires may be released or made available.
`Receiver` | `getReceiver()` Obtains the current receiver to which this transmitter will deliver MIDI messages.
`void` | `setReceiver(Receiver receiver)` Sets the receiver to which this transmitter will deliver MIDI messages.

Method Detail

### setReceiver

    void setReceiver(Receiver receiver)

  Sets the receiver to which this transmitter will deliver MIDI messages. If a receiver is currently set, it is replaced with this one.

  Parameters:
    `receiver` - the desired receiver.

### getReceiver

    Receiver getReceiver()

  Obtains the current receiver to which this transmitter will deliver MIDI messages.

  Returns:
    the current receiver. If no receiver is currently set, returns `null`

### close

    void close()

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

  If the creation of this `Transmitter` 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 `Transmitter` is retrieved from is closed explicitly by calling `MidiDevice.close`, the `Transmitter` is closed, too. For a detailed description of open/close behaviour see the class description of `MidiDevice`.

    `MidiSystem.getTransmitter()`
