Also, make sure that the stall is actually because you're swapping memory &
not because your trying to repaint a large board (look at your OS resource
monitor). You should see almost no CPU usage in user-space if it's memory
swapping.
If it's the CPU, you'll want to do the traditional trick of doing your work
in multiple steps:
private static final STEP_SIZE = 100;
Timer repainter = new Timer() {
public GameResult result;
private GameResult current;
private int row = 0;
private int col = 0;
public void run() {
int steps = 0;
if (current != result) {
row = col = 0;
current = result;
}
ResultGamePlan rGamePlan = current.getGamePlan();
for (; steps < STEP_SIZE && row < gamePlan.getRowCount(); row++)
{
for (; steps < STEP_SIZE && col < gamePlan.getColumnCount();
col++, steps++) {
if (rGamePlan[col][row].equals("B"))
//paint black
else if (rGamePlan[col][row].equals("W"))
// paint white
else
// paint green
}
}
if (row == gamePlan.getRowCount() && col ==
gamePlan.getColumnCount) {
// finished painting
cancel();
current = null;
}
};
/// when you get an update from server
repainter.result = serverResult;
repainter.scheduleRepeating(10);
That'll actually make things slower in terms of throughput, but the UI will
remain responsive, so it'll seem faster.
Another thing you can try is to use initialize like in my previous e-mail,
except use HTML instead of Image.
Then cache the HTML representation of the images in 3 global variables
(getHTML of AbstractImagePrototype). Then when you iterate, simple call
setHTML - that should be even faster & should give you pretty good memory
savings.
