Enclosing interface:

WinBase

public static class WinBase.SYSTEM_INFO
extends Structure

Contains information about the current computer system. This includes the architecture and type of the processor, the number of processors in the system, the page size, and other such information.

processorArchitecture

public WinBase.SYSTEM_INFO.UNION processorArchitecture

Processor architecture (unnamed union).

dwPageSize

public WinDef.DWORD dwPageSize

Page size and the granularity of page protection and commitment.

lpMinimumApplicationAddress

public Pointer lpMinimumApplicationAddress

Pointer to the lowest memory address accessible to applications and dynamic-link libraries (DLLs).

lpMaximumApplicationAddress

public Pointer lpMaximumApplicationAddress

Pointer to the highest memory address accessible to applications and DLLs.

dwActiveProcessorMask

public BaseTSD.DWORD_PTR dwActiveProcessorMask

Mask representing the set of processors configured into the system. Bit 0 is processor 0; bit 31 is processor 31.

dwNumberOfProcessors

public WinDef.DWORD dwNumberOfProcessors

Number of processors in the system.

dwProcessorType

public WinDef.DWORD dwProcessorType

An obsolete member that is retained for compatibility with Windows NT 3.5 and Windows Me/98/95. Use the wProcessorArchitecture, wProcessorLevel, and wProcessorRevision members to determine the type of processor. PROCESSOR_INTEL_386 PROCESSOR_INTEL_486 PROCESSOR_INTEL_PENTIUM

dwAllocationGranularity

public WinDef.DWORD dwAllocationGranularity

Granularity for the starting address at which virtual memory can be allocated.

wProcessorLevel

public WinDef.WORD wProcessorLevel

System's architecture-dependent processor level. It should be used only for display purposes. To determine the feature set of a processor, use the IsProcessorFeaturePresent function. If wProcessorArchitecture is PROCESSOR_ARCHITECTURE_INTEL, wProcessorLevel is defined by the CPU vendor. If wProcessorArchitecture is PROCESSOR_ARCHITECTURE_IA64, wProcessorLevel is set to 1.

wProcessorRevision

public WinDef.WORD wProcessorRevision

Architecture-dependent processor revision.

WinBase.SYSTEM_INFO

public WinBase.SYSTEM_INFO()

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.
