Egret 异步队列处理

1.异步处理器

enum AsyncProcessorEnum {

}

class AsyncProcessor extends egret.EventDispatcher{
    static __pool__ = "AsyncProcessorPool";

    public constructor(){
        super();
    }

    private m_excuting: boolean = false;

    private m_processQueue: any[] = [];

    public addProcess(cb: Function, thisObj?: any, args?: any[], delay?: number) {
        this.m_processQueue.push([cb, thisObj, args, delay]);
    }

    public clearProcess(){
        this.m_processQueue = [];
    }

    public async excuteProcess(){
        if(this.m_excuting) return;
        this.m_excuting = true;

        while(this.m_processQueue.length>0) {
            let cbInfo: any[] = this.m_processQueue.shift();
            let cb:Function = cbInfo[0];
            let thisObj = cbInfo[1];
            let args = cbInfo[2];
            let delay = cbInfo[3];
            cb.apply(thisObj, args);
            await new Promise(resolve=>egret.setTimeout(()=>resolve(1),this,delay));
        }

        this.m_excuting = false;
        this.clearProcess();
    }

}

class GAsyncProcessMgr extends egret.EventDispatcher{
    private static _ins:GAsyncProcessMgr;

    private constructor(){
        super();
    }

    public static get ins():GAsyncProcessMgr{
        if(!this._ins){
            this._ins = new GAsyncProcessMgr();
        }

    }

    private m_processMap: Object = {};

    public addProcess(processId: AsyncProcessorEnum, cb: Function, thisObj?: any, args?: any[], delay?: number) {
        let processor: AsyncProcessor = this.m_processMap[processId];
        if(!processor){
            processor = Pool.getItemByClass(AsyncProcessor.__pool__, AsyncProcessor);
            this.m_processMap[processId] = processor;
        }
        processor.addProcess(cb, thisObj, args, delay);
    }

    public clearAllProcess(){
        for (const processId in this.m_processMap) {
            if (Object.prototype.hasOwnProperty.call(this.m_processMap, processId)) {
                this.clearProcess(processId as AsyncProcessorEnum);
            }
        }
    }

    public clearProcess(processId: AsyncProcessorEnum){
        let processor: AsyncProcessor = this.m_processMap[processId];
        if(!processor){
            return;
        }
        processor.clearProcess();
        Pool.recover(AsyncProcessor.__pool__, processor);
        delete this.m_processMap[processId];
    }

    public excuteProcess(processId: AsyncProcessorEnum){
        let processor: AsyncProcessor = this.m_processMap[processId];
        if(!processor){
            return;
        }
        processor.excuteProcess();
    }
