# Package com.google.gwt.core.client

Fundamental classes used in client-side GWT code. The classes in this package represent concepts fundamental to GWT, such as module entry points, and interfacing with JavaScript.

## Classes

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.
JavaScriptException | Any JavaScript exceptions occurring within JSNI methods are wrapped as this class when caught in Java code.
JavaScriptObject | An opaque handle to a native JavaScript object.

## Interfaces

EntryPoint | Implement this interface to allow a class to act as a module entry point.
