一、字典数据类型的copy函数,当简单的值替换的时候,原始字典和复制过来的字典之间互不影响,但是当添加,删除等修改操作的时候,两者之间会相互影响。 (1)值替换 import copy d = { 'name' : ['An','Assan'] } c = d.copy() dc = copy.deepcopy(d) d['name'] = ['an'] print c print d print ...
这个实例没有去实现ICloneable接口, 也没实现里面的Clone()方法,而是自定义一个Clone()方法; View Code View Code 对于CreateDeepCopy()可以用泛型实现一个通用的Clone()方法 publicstaticT CreateDeepCopy<T>(T item) { BinaryFormatter formatter=newBinaryFormatter(); MemoryStream stream=newMemoryStream(); form...

The implementation of MemberwiseClone would do the following for your code. Person p = new Person(); p.Age = this.Age; // value copy p.Name = this.Name; // value copy p.IdInfo = this.IdInfo; // reference copy. this object is the same in both coppies. return p; Share Improve...

从前面所述可知,深拷贝与浅拷贝的区别主要在于 copy 的层次,浅拷贝 copy 的是第一层对象的引用,深拷贝需要 copy 深层次对象。So,以 deepcopy 层次 Object 为例子,要实现真正的深拷贝操作则需要通过遍历键来赋值对应的值,这个过程中如果遇到 Object 类型还需要再次进行遍历「同样的方法」。递归无疑了。来看波实现...
Unfortunately, "shallow copy", "deep copy" and "clone" are all rather ill-defined terms. In the Java context, we first need to make a distinction between "copying a value" and "copying an object". int a = 1; int b = a; // copying a value int[] s = new int[]{42}; int[]...
