JAVA最快的DEEPCOPY OBJECT java加快编译速度 虚拟机最开始是通过解释器进行解释执行的,解释器是最基础的,但是没有优化,效率和速度都有待提高。但是只依靠解释器不进行优化也是可以的。即时编译器和提前编译器都是采取的优化措施,是可选择的。 即时编译器:当虚拟机发现某个方法或代码块的运行特别频繁,就会把这些代码认...
场景:MVVM模式中数据双向绑定,想实现编辑、保存、撤销操作时也双向绑定了,不能实现撤销操作。 后来通过搜索找到了继承IEditableObject接口实现撤销操作,但是对其中使用了MemberwiseClone还不是很了解。 MemberwiseClone: https://msdn.microsoft.com/zh-cn/library/system.object.memberwiseclone(v=vs.110)...

} public static Object Copy(this Object originalObject) { return InternalCopy(originalObject, new Dictionary<Object, Object>(new ReferenceEqualityComparer())); } private static Object InternalCopy(Object originalObject, IDictionary<Object, Object> visited) { if (originalObject == null) return null;...
This creates the need for a method to deep clone the object. This tutorial teaches how to deep clone an object in JavaScript. Shallow Copy vs Deep Copy A shallow copy is a bitwise copy of the object. The new object created successfully copies the primitives like numbers, boolean, and ...
