Package cn.mapway.ui.client.frame

Class ModuleDispatcher

java.lang.Object

cn.mapway.ui.client.frame.ModuleDispatcher

All Implemented Interfaces:

IEventHandler, IModuleDispatcher, IShowMessage

public class ModuleDispatcher
extends Object
implements IModuleDispatcher, IEventHandler, IShowMessage

ModuleDispatcher 有两种事件的发生 会调度到这个模块调度器 1. 直接调用本类提供的接口 switchModule 2.接受来自 eventBus 上的模块调度消息 -调度模块 -返回之前的模块

关于 URL中Hash 1.之前版本中的hash只支持一级模块 #2A3F12 2.变更之后支持多级模块的调度 #2A3F12;34490;443443
