Components are stateful, so maybe you could just keep the
state in your Link?
@Override onClick() {
if (!isEnabled()) {
return; // this shouldnt happen though?
}
try {
setEnabled(false);
doSomeHeavyWeightProcessing();
} finally {
setEnabled(true);
}
}
This creates a little race condition but if you can produce
it you could try using a real lock mechanism.
Best wishes,
