public static class Guid.REFIID extends PointerType
REFIID is a pointer to an IID.

This type needs to be seperate from IID, as the REFIID can be passed in from external code, that does not allow writes to memory.

With the normal JNA behaviour a structure, that crosses the native<-%gt;Java border will be autowritten, which causes a fault when written. Observed was this behaviour in COM-Callbacks, which get the REFIID passed into Invoke-method.

So a IID can't be used directly, although the typedef of REFIID (from MSDN):

typedef IID* REFIID;

and the jna behaviour is described as:

"When a function requires a pointer to a struct, a Java Structure should be used."

    • equals

      public boolean equals(Object o)
      Description copied from class: PointerType
      Instances of PointerType with identical pointers compare equal by default.

    • hashCode

      public int hashCode()
      Description copied from class: PointerType
      The hash code for a PointerType is the same as that for its pointer.
      Overrides:
