FIELDS

public static final java.util.List<java.lang.String> FIELDS

cbSize

public int cbSize

The size, in bytes, of the SP_DEVINFO_DATA structure.

InterfaceClassGuid

public Guid.GUID InterfaceClassGuid

The GUID of the device's setup class.

DevInst

public int DevInst

An opaque handle to the device instance (also known as a handle to the devnode). Some functions, such as SetupDiXxx functions, take the whole SP_DEVINFO_DATA structure as input to identify a device in a device information set. Other functions, such as CM_Xxx functions like CM_Get_DevNode_Status, take this DevInst handle as input.

Reserved

public Pointer Reserved

Reserved. For internal use only.

Method Detail

getFieldOrder

protected java.util.List<java.lang.String> 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.

Specified by:

getFieldOrder in class Structure

Returns:

ordered list of field names
