Virtual Grid? First Step..
Hi all,
Finally, we succeeded. We have a first draft of the Virtual Grid. The work was divided into two steps.
The first step..
It was to manage the methods needed to manage the virtual paradigm. Methods like doClear and others have been implemented thanks to the paradigm of DataVisualizer Grid.
The second step..
It was to improve the Grid performance.
Using the tool JVisualVM, i found the bottleneck. This is the method Grid.getIndexOfItem. It calls the indexOf method of the collection items which have low performance in the collections of large amounts objects. Avoiding this method, there was a significant increase in performance.
The result is that..
Today, Grid Nebula is much more powerful and can handle more data using less memory. GridTableViewer becomes a viable alternative to JFace TableViewer. The two are easily interchangeable, since they have much in common.
