Class DefermentWriter

java.lang.Object

xapi.dev.util.DefermentWriter

public class DefermentWriter
extends Object

A utility class for wrapping injected content within a deferred command. It takes a standard gwt-dev SourceWriter, and allows you to choose from a number of deferment strategies; its primary use is in the core api is to enforce asynchronicity when using callbacks during singleton injection. If a splitpoint is already loaded when you request the code, it will immediately execute your callback. Using deferment allows you to ensure asynchronous timing remains deterministic.
