Examples of gov.nasa.arc.mct.util.internal.ElapsedTimer

gov.nasa.arc.mct.util.internal.ElapsedTimer
Provide a timer than can be used for performance monitoring. The timer provides overall time as well as elapsed time.

    
    protected class NodeViewManifestationListener extends AbstractViewListener {
        
        @Override
        public void actionPerformed(TreeExpansionEvent event) {
            final ElapsedTimer timer = new ElapsedTimer();
            timer.startInterval();
            
            JTree tree = (JTree) event.getSource();
            final DefaultTreeModel treeModel = (DefaultTreeModel) tree.getModel();


            final MCTMutableTreeNode selectedNode = node;


            AbstractComponent component = getManifestedComponent();


            for (AbstractComponent childComponent : component.getComponents()) {
                Set<ViewInfo> nodeViews = childComponent.getViewInfos(ViewType.NODE);
                if (!nodeViews.isEmpty()) {
                    ViewInfo nextViewInfo = nodeViews.iterator().next();
                    
                    // Children are only allowed if the component is not a leaf or the component is another users drop box
                    boolean allowsChildren =!childComponent.isLeaf();
                    
                    View childNodeView = nextViewInfo.createView(childComponent);
                    MCTMutableTreeNode childNode = new MCTMutableTreeNode(childNodeView, tree, allowsChildren);


                    if (allowsChildren){
                        MCTMutableTreeNode grandChildNode = new MCTMutableTreeNode(View.NULL_VIEW_MANIFESTATION, tree);
                        childNode.add(grandChildNode);
                        childNode.setProxy(true);
                    }
                    selectedNode.add(childNode);
                    childNodeView.addPropertyChangeListener(VIEW_STALE_PROPERTY, objectStaleListener);
                }
            }
            treeModel.reload(selectedNode);
            
            timer.stopInterval();
            PERF_LOGGER.debug("Time to expand node {}: {}", component.getId(), timer.getIntervalInMillis());
