java.lang.Object
  com.jniwrapper.win32.system.MemoryInfo

public class MemoryInfo
extends java.lang.Object

Class allows to obtain information about the current state of both physical and virtual memory, including extended memory.
Function uses GlobalMemoryStatusEx API funciton and MemoryStatusEx structure for getting information starting from Windows2000 and higher versions.
The GlobalMemoryStatus API funciton and MemoryStatus structure are being used on earlier versions of operating systems.
