Method Summary

Modifier and Type	Method	Description
void	fieldSlotWalkFunction(WalkState walkState, ObjectReferencePointer objectSlot, VoidPointer stackLocation)	This callback doesn't exist in the native C.
FrameCallbackResult	frameWalkFunction(WalkState walkState)
void	objectSlotWalkFunction(WalkState walkState, PointerPointer objectSlot, VoidPointer stackLocation)

Method Detail

frameWalkFunction

FrameCallbackResult frameWalkFunction(WalkState walkState)

objectSlotWalkFunction

void objectSlotWalkFunction(WalkState walkState,
                            PointerPointer objectSlot,
                            VoidPointer stackLocation)

fieldSlotWalkFunction

void fieldSlotWalkFunction(WalkState walkState,
                           ObjectReferencePointer objectSlot,
                           VoidPointer stackLocation)

This callback doesn't exist in the native C. It's purpose in DDR is passing back field slots in stack-allocated objects (which would be incorrectly handled by a PointerPointer)
