对kline.js的自定义修改

import {CName} from './cname'

export class NamedObject {

    constructor(name) {
        this._name = name;
        this._nameObj = new CName(name);
    }

    }

    }

        return this._nameObj.getName(2);
    }

    getName() {
        return this._nameObj.getName(-1);
    }

    getNameObject() {
        return this._nameObj;
    }
