Interface Summary

Interface	Description
AsyncProvider<T,F>	An object capable of providing an instance of type T asynchronously via Callback.
Callback<T,F>	A callback for any asynchronous call that can result in success or failure.
EntryPoint	Implement this interface to allow a class to act as a module entry point.
GWT.UncaughtExceptionHandler	This interface is used to catch exceptions at the "top level" just before they escape to the browser.

Scheduler.RepeatingCommand	General-purpose Command interface for tasks that repeat.
Scheduler.ScheduledCommand	General-purpose Command interface.

Class Summary

Class	Description
Duration	A utility class for measuring elapsed time.
GWT	Supports core functionality that in some cases requires direct support from the compiler and runtime systems such as runtime type information and deferred binding.
GWTBridge	When running in Development Mode, acts as a bridge from GWT into the Development Mode environment.
JavaScriptObject	An opaque handle to a native JavaScript object.
JsArray<T extends JavaScriptObject>	A simple wrapper around a homogeneous native array of JavaScriptObject values.
JsArrayBoolean	A simple wrapper around a homogeneous native array of boolean values.
JsArrayInteger	A simple wrapper around a homogeneous native array of integer values.
JsArrayMixed	A simple wrapper around an heterogeneous native array of values.
JsArrayNumber	A simple wrapper around a homogeneous native array of numeric values.
JsArrayString	A simple wrapper around a homogeneous native array of string values.
JsArrayUtils	Utility class for manipulating JS arrays.
JsDate	A simple wrapper around a native JS Date object.
JsonUtils	Provides JSON-related utility methods.
Scheduler	This class provides low-level task scheduling primitives.
ScriptInjector	Dynamically create a script tag and attach it to the DOM.
ScriptInjector.FromString	Builder for directly injecting a script body into the DOM.
ScriptInjector.FromUrl	Build an injection call for adding a script by URL.

Enum Summary

Enum	Description
CodeDownloadException.Reason	Reason codes for the interruption of code down load.

Annotation Types Summary

Annotation Type	Description
GwtScriptOnly	Deprecated since hosted/dev mode is deprecated and has no other uses.
SingleJsoImpl	This annotation may be placed on an interface to declare the single JavaScriptObject type that implements the interface.
SingleJsoImplName	This annotation may be placed on an interface to name the single JavaScriptObject type that implements the interface.
UnsafeNativeLong	This annotation can be placed on a native method to allow it to directly access Java long values.
