You cannot create objects from abstract classes.
Creating objects unnecessarily merely affects style and performance.用友运行时错误429,activex部件不能创建对象。
He was facing Run-time error 429:ActiveX Component cannot create object.
Figure 8.3 Creating objects with simple definitions.用友运行时错误429,activex部件不能创建对象。
Error: 429 Active X Component cannot Create Object.Combinations with other parts of speech
Error: 429 Active X Component cannot Create Object.创建一个构造函数使用3种方法创建对象的Calculator:.
Create a constructor function Calculator that creates objects with 3 methods:.
Example 6 Access member of newly created object.
Once you have created the objects, you can even print them out.
The key word‘new' is used for creation of objects.由于外部构造方法只能通过调用其它的构造方法来创建对象,所以最终构造对象的一定是某个内部构造函数。
Since outer constructor methods can only create objects by calling other constructor methods, ultimately, some inner constructor must be called to create an object..创建对象可能会导致大量的重复代码,也可能提供不了足够级别的抽象。
Object creation may lead to a significant duplication of code and not provide a sufficient level of abstraction.
The factory pattern is a class that has some methods that create objects for you.在前面的两个示例中,继承的原型可以为所有对象共享,不必在每一次创建对象时定义方法。
In the two previous examples, the inherited prototype can be shared by all objects andthe method definitions need not occur at every object creation.一、工厂模式是一种类,它具有为您创建对象的某些方法。
The factory pattern is a class that has some methods that create objects for you.有了OOP,你可以通过创建对象把这些复杂的问题划分成更小的集合。
With OOP,the programmer can split these problematic problems into smaller parts by creating objects.有了OOP,你可以通过创建对象把这些复杂的问题划分成更小的集合。
With OOP,you are able to divide these complex problems into smaller sets by creating objects.在工厂模式中,我们创建对象而不将创建逻辑暴露给客户端。
In Factory pattern, we create object without exposing the creation logic.Javascript不具有像C++、Smalltalk、Java那样的真正的类,但是支持创建对象的构造器。
ECMAScript does not contain proper classes such as those in C++, Smalltalk, or Java, but rather,supports constructors which create objects.跟例子中的类A,B,C相似,在ECMAScript中你创建对象:a,b,c。
Similarly like in the example with classes A, B and C, in ECMAScript you create objects: a, b, and c.在这一章中,我们将学习C++的new和delete如何漂亮地通过在堆上安全地创建对象而解决上述问题。
In this chapter, you will learn how C++'s new anddelete elegantly solve this problem by safely creating objects on the heap.一个更灵活但不太安全的设计是给创建对象的操作增加一个参数。
A more flexible butless safe design is to add a parameter to operations that create objects.Java中基于对象的应用程序基于声明类,从它们创建对象以及这些对象之间的交互。
An object-based application inJava is based on declaring classes, creating objects from them and interacting between these objects..工厂模式工厂模式是一种类,它具有为您创建对象的某些方法。
The factory pattern is a class that has some methods that create objects for you.注意:像刚才展示的那样使用“构造形式”来创建对象是极其少见的。
Note: It's extremely uncommon to use the"constructed form" for creating objects as just shown.除此之外,Sciaky还提供了一个双进料系统,可以同时使用两种不同的金属材料创建对象。
Sciaky also offers a dual feed system that can create objects from two different metal materials at the same time.
If you need a reminder on how to create objects, check the previous unit.封装(第1部分):创建对象后,使用它并不需要了解它的实现。
Encapsulation(part 1): Once an Object is created, knowledge of its implementation is not necessary for its use.
