olympus-r/engine/env/Query.js

一个力求简单易用的前端开发框架 #### 开发语言 TypeScript #### 核心架构 MVC #### 模块间通讯和解耦 采用事件机制，利用一个全局唯一的事件派发器进行模块间通讯，解耦模块间依赖 #### 表现层结构 使用桥接模式拆分接口与实现，达到一套核心驱动多套表现层的目的（目前支持DOM、Egret、PixiJS三种表现层），同时支持表现层的未来可扩展性 #### TypeScript装饰器注入 框架提供TypeScript装饰器注入功能，便捷获取托管对象。例如：

import * as tslib_1 from "tslib";
import { core } from "../../core/Core";
import { Injectable } from "../../core/injector/Injector";
