WinDef.DWORD |
dwLength
The size of the structure, in bytes. |
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). |

Reserved. |
WinDef.DWORDLONG |
ullAvailPageFile
The maximum amount of memory the current process can commit, in bytes. |
WinDef.DWORDLONG |
ullAvailPhys
The amount of physical memory currently available, in bytes. |
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. |
WinDef.DWORDLONG |
ullTotalPageFile
The current committed memory limit for the system or the current process, whichever is smaller, in bytes. |
WinDef.DWORDLONG |
ullTotalPhys
The amount of actual physical memory, in bytes. |
WinDef.DWORDLONG |
ullTotalVirtual
The size of the user-mode portion of the virtual address space of the calling process, in bytes. |

protected List getFieldOrder()
Structure
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.
