- ## Field Details

  - ### nodeNumber

    public int nodeNumber
    Identifies the NUMA node. Valid values are `0` to the highest NUMA node number inclusive. A non-NUMA multiprocessor system will report that all processors belong to one NUMA node.

  - ### reserved

    public byte[] reserved
    This member is reserved.

  - ### groupCount

    public short groupCount
    The number of groups included in the GroupMasks array. This field was introduced in TBD Release Iron. On earlier versions, this value is always 0.

  - ### groupMask

    public WinNT.GROUP_AFFINITY groupMask
    A `WinNT.GROUP_AFFINITY` structure that specifies a group number and processor affinity within the group. This member is only relevant if `groupCount` is 0.

  - ### groupMasks

    public WinNT.GROUP_AFFINITY[] groupMasks
    An array of `WinNT.GROUP_AFFINITY` structures that specifies a group number and processor affinity within the group. This member is only relevant if `groupCount` is 1 or greater.

  - ### read

    public void read()
    Description copied from class: `Structure`
    Reads the fields of the struct from native memory

    protected List<Field> getFieldList()
    Description copied from class: `Structure`
    Look up all fields in this class and superclasses.
    Overrides:
      `getFieldList` in class `Structure`
    Returns:
      ordered list of public `Field` available on this `Structure` class.
