casper clone

I. The concept of shallow cloning and deep cloning: 1). Shallow clone: Also known as shallow copy, all variables of the copied object contain the same value as the original object, and all references to other objects still point to the original object. In other words, a shallow copy simply duplicates the object being considered, not the object it refers to.2). Deep clone: Also known as deep copy, all variab

PHP object clone clone keyword and __clone () method The Clone keyword is used to clone an identical object, and the __clone () method overrides the original property and method. Object cloning Sometimes we need to use two or more of the same objects in a project, and it is cumbersome and error-prone to re-create ob

From php.net: In most cases, we do not need to completely copy an object to obtain its attributes. However, you need to: If you have a GTK window object, the object holds window-related resources. You may want to copy a new window to keep all at

Cloning is a new object created as a copy of the current instance. Cloning can be divided into deep cloning and shortest cloning. Deep clone: All members of the current instance are cloned. Simple clone: Only all values of the current instance are cloned. The simple clone Object class provides us with a protected clone

That there's some good in the world, Mr Frodo. And it ' s worth fighting for.Prototype mode (prototype), which specifies the kind of object created with the prototype instance, and creates a new object by copying the prototypes.As for Object.clone (), we will not dwell on it here. The document may seem a little confusing, and the code is easier to understand:Shallow clone:1 Package Cn.happy.design_pattern._06prototype.shallowclone;2 3 Public Abstract

PHP object replication, is a copy of the object's reference address, so use $objA = $objB this style, $objA and $OBJB will point to the same memory address. $objB can also be affected when the $obja is changed. If we want to replicate $obja objects as $OBJB objects, what changes $objA after replication will not affect $OBJB. That is, $obja and $OBJB are two separate objects, but $OBJB's initial values are created by $obja, and the more efficient approach is to use the

Today we will talk about the BSP clone of wince, which is actually a BSP copy, but it only changes the information in some BSP. In wince, the cloning of BSP should be very simple. Today we will give a brief introduction.I seldom use BSP cloning. I have been using wince for several years. I used it several times. I first tried it several times to learn how to clone it, but it has no practical use. Later, I w

1. Why rewrite the Clone () method?The shallow copy in Java does not re-create a new reference space for the object that you want to copy, and we'll rewrite the Clone () method when we need a deep copy.2.
