Javascript面向对象基础以及接口和继承类的实现(1)(2)

Interface.registerImplements = function(object) { 

    if(arguments.length < 2) {
        throw new Error("接口的实现必须包含至少2个参数.");
    } 

    for(var i = 1, len = arguments.length; i < len; i++) {
        var interface = arguments[i];
        if(interface.constructor !== Interface) {
            throw new Error("从第2个以上的参数必须为接口实例.");
        }
        for(var j = 0, methodsLen = interface.methods.length; j < methodsLen; j++) {
            var method = interface.methods[j][0];
            if(!object[method] || typeof object[method] !== 'function' || object[method].getParameters().length != interface.methods[j][1]) {
                throw new Error("接口的实现对象不能执行" + interface.name + "的接口方法" + method + "，因为它找不到或者不匹配.");
            }
        }
    }
};
