Package bradleyross.music.MidiRouter

Class RelationshipTest

java.lang.Object

bradleyross.music.MidiRouter.RelationshipTest

All Implemented Interfaces:

java.lang.Runnable

public class RelationshipTest
extends java.lang.Object
implements java.lang.Runnable

Test whether MidiDevice.Info.getMidiDevice always gives the same object.

Three MidiDevice objects are created from the same MidiDevice.Info object. The same object should be returned in each case. This is not true for the synthesizer and sequencer.

A MidiDevice.Info object was created from each of the MidiDevice objects. The hash code should be the same for each of the three cases. This appears to be the case.

Question: If two identical MIDI keyboards are attached at the same time, will they have different hash codes?
