所谓的 shallow copy,以 dataframe 为例,就是不对数据进行我们常规意义上的复制,其实复制的内容只是数据在内存的地址,也就是和原数据指向了同一内存的地址,导致修改复制的数据,同样会修改原始的数据。 而对于 deep copy 则就是我们通常意义上的操作,又复制了一份数据,在不同的内存的位置上,修改不同位置上的数据,...
Creates a shallow copy of the current System.Object. Return Values: A shallow copy of the current System.Object. This indicates to me that a memberwiseclone is a shallow copy not a deep copy as you have stated above. So I am still confused as to the correct definitions of a memberwise,...

There are API differences depending on whether the OpenEXR part being read contains scanline data or tiled data, and to handle deep vs shallow image files. However, largely all the same functions are used to read and write this atomic data....
上面给出的实现叫作对象的“浅拷贝”(shallow copy),与之相对,“深拷贝”是指检查准备复制的属性本身是否是对象或者数组,如果是,也遍历它们的属性并复制。如果使用浅拷贝的话(因为在JavaScript中对象是按引用传递),如果你改变子对象的一个属性,而这个属性恰好是一个对象,那么你也会改变父对象。实际上这...
