public class Pointer
extends Object
```
An abstraction for a native pointer data type. A Pointer instance represents, on the Java side, a native pointer. The native pointer could be any type of native pointer. Methods such as write, read, getXXX, and setXXX, provide means to access memory underlying the native pointer.
While a constructor exists to create a Pointer from an integer value, it's not generally a good idea to be creating pointers that way.
