Enclosing interface:

WinBase

public static class WinBase.MEMORYSTATUSEX
extends Structure

Contains information about the current state of both physical and virtual memory, including extended memory. The GlobalMemoryStatusEx function stores information in this structure.

dwLength

public WinDef.DWORD dwLength

The size of the structure, in bytes.

dwMemoryLoad

public WinDef.DWORD dwMemoryLoad

A number between 0 and 100 that specifies the approximate percentage of physical memory that is in use (0 indicates no memory use and 100 indicates full memory use).

ullTotalPhys

public WinDef.DWORDLONG ullTotalPhys

The amount of actual physical memory, in bytes.

ullAvailPhys

public WinDef.DWORDLONG ullAvailPhys

The amount of physical memory currently available, in bytes. This is the amount of physical memory that can be immediately reused without having to write its contents to disk first. It is the sum of the size of the standby, free, and zero lists.

ullTotalPageFile

public WinDef.DWORDLONG ullTotalPageFile

The current committed memory limit for the system or the current process, whichever is smaller, in bytes.

ullAvailPageFile

public WinDef.DWORDLONG ullAvailPageFile

The maximum amount of memory the current process can commit, in bytes. This value is equal to or smaller than the system-wide available commit value.

ullTotalVirtual

public WinDef.DWORDLONG ullTotalVirtual

The size of the user-mode portion of the virtual address space of the calling process, in bytes.

ullAvailVirtual

public WinDef.DWORDLONG ullAvailVirtual

The amount of unreserved and uncommitted memory currently in the user-mode portion of the virtual address space of the calling process, in bytes.

ullAvailExtendedVirtual

public WinDef.DWORDLONG ullAvailExtendedVirtual

Reserved. This value is always 0.

WinBase.MEMORYSTATUSEX

public WinBase.MEMORYSTATUSEX()

getFieldOrder

protected List getFieldOrder()

Description copied from class: Structure

Return this Structure's field names in their proper order. For example,

 protected List getFieldOrder() {
     return Arrays.asList(new String[] { ... });
 }
 

IMPORTANT When deriving from an existing Structure subclass, ensure that you augment the list provided by the superclass, e.g.

 protected List getFieldOrder() {
     List fields = new ArrayList(super.getFieldOrder());
     fields.addAll(Arrays.asList(new String[] { ... }));
     return fields;
 }
 

Field order must be explicitly indicated, since the field order as returned by Class.getFields() is not guaranteed to be predictable.
