Class DeferredCommand

java.lang.Object
  com.google.gwt.user.client.DeferredCommand

@Deprecated
public class DeferredCommand
extends java.lang.Object

This class allows you to execute code after all currently pending event handlers have completed, using the addCommand(Command) or addCommand(IncrementalCommand) methods. This is useful when you need to execute code outside of the context of the current stack.

DeferredCommand

public DeferredCommand()

Deprecated. 

add

@Deprecated
public static void add(Command cmd)

Deprecated. As of release 1.4, replaced by addCommand(Command)

Enqueues a Command to be fired after all current events have been handled.

Parameters:

cmd - the command to be fired. If cmd is null, a "pause" will be inserted into the queue. Any events added after the pause will wait for an additional cycle through the system event loop before executing. Pauses are cumulative.

addCommand

public static void addCommand(Command cmd)

Deprecated. 

Enqueues a Command to be fired after all current events have been handled. Note that the Command should not perform any blocking operations.

Parameters:

cmd - the command to be fired

Throws:

java.lang.NullPointerException - if cmd is null

addCommand

public static void addCommand(IncrementalCommand cmd)

Deprecated. 

Enqueues an IncrementalCommand to be fired after all current events have been handled. Note that the IncrementalCommand should not perform any blocking operations.

Parameters:

cmd - the command to be fired

Throws:

java.lang.NullPointerException - if cmd is null

addPause

@Deprecated
public static void addPause()

Deprecated. with no replacement because the presence of this method causes arbitrary scheduling decisions

Adds a "pause" to the queue of DeferredCommands. Any DeferredCommands or pauses that are added after this pause will wait for an additional cycle through the system event loop before executing.
