Tips to improve performance on IlpNetwork

Question

What are the IlpNetwork-specific tips that I can use to improve performance?

Answer

Use the following tips:

1. Disable time-consuming services during end-user interactions

   When dragging objects, you can delay the layout or draw ghosts instead of fully opaque objects.

   For example, to disable the layout temporarily, you can make the followingcall, let's say in your interactor:

   //Prior to starting the changes
   IlvManager.setContentsAdjusting(true);
   ...
   //move, drag, some other operation
   ...
   //After operation is done
   IlvManager.setContentsAdjusting(false);

   You can also make use of:

   IlvGraphLayout.setAutoLayout (boolean)

   You can change how and when dragged objects are drawn by using the following

   API:

   IlvSelectInteractor.setOpaqueMove (boolean set)
   IlvSelectInteractor.setXORGhost (boolean xorGhost)

2. Make use of the start/endBatch() methods

   You should make use of the

   startBatch() and endBatch() methods of the IlpAbstractDataSource class before and after making massive changes to the IlpObject instances in the data source. This has proven to make computation almost 5 times faster in certain cases.

   IlpAbstractDataSource datasource = (IlpAbstractDataSource)network.getDataSource();
datasource.startBatch();
for (all network elements) {
networkElement = objects.next();
updateStatesAndAlarms(networkElement);
}
datasource.endBatch();
