Example 1 with VmOperationEvent

use of com.tagtraum.perf.gcviewer.model.VmOperationEvent in project GCViewer by chewiebug.

the class ModelMetricsPanelTest method testVmOpModel.

@Test
public void testVmOpModel() {
    GCEvent event = new GCEvent();
    event.setTimestamp(0.5);
    event.setType(Type.G1_YOUNG_INITIAL_MARK);
    event.setPause(0.245);

    event.setPostUsed(400);
    event.setTotal(1024);
    GCModel model = new GCModel();
    model.add(event);
    VmOperationEvent vmOpEvent = new VmOperationEvent();
    vmOpEvent.setTimestamp(0.7);
    vmOpEvent.setType(Type.APPLICATION_STOPPED_TIME);
    vmOpEvent.setPause(0.26);
    model.add(vmOpEvent);
    ModelMetricsPanel panel = new ModelMetricsPanel();
    // first add empty model; is done when opened
    panel.setModel(new GCModel());
    // only later a model with entries is set
    panel.setModel(model);
