public void	runTests() Runs all tests. declare("testCreate"); testCreate(); declare("testRegister"); testRegister(); declare("testGrowDispatchTable"); testGrowDispatchTable(); declare("testPost1"); testPost1(); declare("testPost3"); testPost3(); declare("testPreprocess"); testPreprocess();
void	testCreate() Test simple creation of an event queue. EventQueue eq = new EventQueue(); assertFalse(eq.alive); assertNotNull(eq.dispatchTable); assertTrue(eq.dispatchTable.length > 0); assertNotNull(eq.pool); assertEquals(-1, eq.nativeEventQueueHandle); assertNotNull(eq.eventQueueThread); assertNotNull(eq.eventMonitorThread); assertFalse(eq.eventQueueThread.isAlive()); assertFalse(eq.eventMonitorThread.isAlive());
void	testGrowDispatchTable() Tests whether the dispatch table is grown properly. final int EVENT_TYPE_A = 4; final int EVENT_TYPE_B = 97; // must be larger than the dispatch table default size EventQueue eq = new EventQueue(); assertTrue(EVENT_TYPE_B > eq.dispatchTable.length); InstrumentedEventListener iela = new InstrumentedEventListener(); InstrumentedEventListener ielb = new InstrumentedEventListener(); eq.registerEventListener(EVENT_TYPE_A, iela); eq.registerEventListener(EVENT_TYPE_B, ielb); DispatchData dda = eq.dispatchTable[EVENT_TYPE_A-1]; assertNotNull(dda); assertEquals(iela, dda.listener); DispatchData ddb = eq.dispatchTable[EVENT_TYPE_B-1]; assertNotNull(ddb); assertEquals(ielb, ddb.listener);
void	testPost1() Tests posting of an event. final int EVENT_TYPE = 14; EventQueue eq = new EventQueue(); InstrumentedEventListener iel = new InstrumentedEventListener(); eq.registerEventListener(EVENT_TYPE, iel); Event ev = new Event(EVENT_TYPE); eq.post(ev); // assertions on the event queue assertSame("nextEvent should be ev", ev, eq.nextEvent); assertSame("lastEvent should be ev", ev, eq.lastEvent); // assertions from the event listener Event[] arr; arr = iel.getProcessedEvents(); assertEquals("processed should be length 0", 0, arr.length); arr = iel.getPreprocessedEvents(); assertEquals("preprocessed should be length 1", 1, arr.length); assertSame("preprocessed[0] should be ev", ev, arr[0]); arr = iel.getWaitingEvents(); assertEquals("waiting should be length 1", 1, arr.length); assertNull("waiting[0] should be null", arr[0]);
void	testPost3() Tests posting of three events. final int EVENT_TYPE_A = 5; final int EVENT_TYPE_B = 7; EventQueue eq = new EventQueue(); InstrumentedEventListener iel = new InstrumentedEventListener(); eq.registerEventListener(EVENT_TYPE_A, iel); eq.registerEventListener(EVENT_TYPE_B, iel); Event ev0 = new Event(EVENT_TYPE_A); Event ev1 = new Event(EVENT_TYPE_B); Event ev2 = new Event(EVENT_TYPE_A); eq.post(ev0); eq.post(ev1); eq.post(ev2); // assertions on the event queue assertSame("nextEvent should be ev0", ev0, eq.nextEvent); assertSame("lastEvent should be ev2", ev2, eq.lastEvent); assertSame("ev0.next should be ev1", ev1, ev0.next); assertSame("ev1.next should be ev2", ev2, ev1.next); assertNull("ev2.next should be null", ev2.next); // assertions from the event listener Event[] arr; arr = iel.getProcessedEvents(); assertEquals("processed should be length 0", 0, arr.length); arr = iel.getPreprocessedEvents(); assertEquals("preprocessed should be length 3", 3, arr.length); assertSame("preprocessed[0] should be ev0", ev0, arr[0]); assertSame("preprocessed[1] should be ev1", ev1, arr[1]); assertSame("preprocessed[2] should be ev2", ev2, arr[2]); arr = iel.getWaitingEvents(); assertEquals("waiting should be length 3", 3, arr.length); assertNull("waiting[0] should be null", arr[0]); assertNull("waiting[1] should be null", arr[1]); assertEquals("waiting[2] should be ev0", ev0, arr[2]);
void	testPreprocess() Tests preprocessing of events. EventQueue eq = new EventQueue(); InstrumentedEventListener iel = new InstrumentedEventListener(true); final int EVENT_TYPE = 10; eq.registerEventListener(EVENT_TYPE, iel); Event ev0 = new Event(EVENT_TYPE); Event ev1 = new Event(EVENT_TYPE); eq.post(ev0); iel.setPreprocess(false); eq.post(ev1); // assertions on the event queue assertSame("nextEvent should be ev0", ev0, eq.nextEvent); assertSame("lastEvent should be ev0", ev0, eq.lastEvent); assertNull("ev0.next should be null", ev0.next); // assertions from the event listener Event[] arr; arr = iel.getProcessedEvents(); assertEquals("processed should be length 0", 0, arr.length); arr = iel.getPreprocessedEvents(); assertEquals("preprocessed should be length 2", 2, arr.length); assertSame("preprocessed[0] should be ev0", ev0, arr[0]); assertSame("preprocessed[1] should be ev1", ev1, arr[1]); arr = iel.getWaitingEvents(); assertEquals("waiting should be length 2", 2, arr.length); assertNull("waiting[0] should be null", arr[0]); assertEquals("waiting[1] should be ev0", ev0, arr[1]);
void	testRegister() Tests the ability to register an event. final int EVENT_TYPE = 7; EventQueue eq = new EventQueue(); InstrumentedEventListener iel = new InstrumentedEventListener(); eq.registerEventListener(EVENT_TYPE, iel); DispatchData dd = eq.dispatchTable[EVENT_TYPE-1]; assertNotNull(dd); assertEquals(iel, dd.listener);
