Class CommandExecutor

java.lang.Object

com.google.gwt.user.client.CommandExecutor

public static class CommandExecutor
extends Object

Class which executes Commands and IncrementalCommands after all currently pending event handlers have completed. This class attempts to protect against slow script warnings by running commands in small time increments.

It is still possible that a poorly written command could cause a slow script warning which a user may choose to cancel. In that event, a CommandCanceledException or an IncrementalCommandCanceledException is reported through GWT#reportUncaughtException depending on the type of command which caused the warning. All other commands will continue to be executed.

TODO(mmendez): Can an SSW be detected without using a timer? Currently, if a Command or an IncrementalCommand calls either Window.alert(String) or the JavaScript alert(String) methods directly or indirectly then the cancellation timer can fire, resulting in a false SSW cancellation detection.
