Shallow copy, in C#, is the process of creating a clone of an object by instantiating a new instance of the same type as original object and copying the non-static members of the existing object to the clone. The members of the value type are copied bit by bit while the members of th...
public Foo shallowCopy() { Foo newFoo = new Foo(); newFoo.myBar = myBar; return newFoo; } public Foo deepCopy() { Foo newFoo = new Foo(); newFoo.myBar = myBar.clone(); //or new Bar(myBar) or myBar.deepCopy or ... return newFoo; } } Foo myFoo = new Foo(); Foo...
What’s the difference between deep copy and shallow copy (深拷贝与浅拷贝有什么区别)相关知识点: 试题来源: 解析 答:浅拷贝是指将对象中的数值类型的字段拷贝到新的对象中,而对象中的引用型字段则指复制它的一个引用到目标对象。如果改变目标对象中引用型字段的值他将反映在原是对象中,也就是说原始对象中...

I think it is. So is X=Y above equivalent to using ICloneable to produce a shallow copy clone ("return (this.Memberwis eClone());"), or is it more like a deep copy ("return (BinaryFormatte r1.Deserialize( memStream));")? RL It's neither if MyObject is a class. in that ...
you can pass a pointer to a local object, and since it is synchronous, the object outlives the message handler, assuming the handler doesn't retain a copy of the pointer. However, with PostMessage, you will usually have to use new/delete, e.g. to pass a CString in PostMessage (I ...
