如果类型仅包含值类型(int,byte等类型)和string类型的数据成员, 我们只要在Clone方法中初始化一个新的对象,将其的数据成员设置为当前对象的各个成员的值即可。事实上,object类的 MemberwiseClone方法会自动完成该过程。 如果自定义类型包含引用类型的数据成员,必须考虑Clone方法是实现浅拷贝(shallow copy)还是深拷贝(deep...

C.130:实现多态类的深拷贝时,虚clone函数要比拷贝构造函数/赋值运算符好。 Reason(原因) Copying a polymorphic class is discouraged due to the slicing problem, see C.67. If you really need copy semantics, copy deeply: Provide a virtual clone function that will copy the actual most-derived ty...
Java 中实现数组复制有 4 种方法,分别为使用 Arrays 类的 copyOf() 方法和 copyOfRange() 方法、System 类的 arraycopy() 方法和 Object 类的 clone() 方法。下面来详细介绍这 4 种方法的使用。 04 【算法基础】数组扩容、缩容 问题: 现有数组 int[] arr = new int[]{1,2,3,4,5,6}; ,现将数组...

或者使用clone() y = x:clone() 下面我们看Tensor的methods,如果你想操作不同类型的Tensor,使用CharTensor即可。 Tensor有很多methods。像add,mul,填充fill,更改大小,获取子矩阵等。 这里就查看一个比较特殊的methods吧, [Tensor] gather(dim, index)
