byref
Wraps up this object in a pointer that can be passed to native code. The byref() return value cannot be used as anything other than a parameter.- Returns:
- A ByReference instance pointing to this object's native memory.
-
pointer
-
address
-
getReferenceMemory
Returns the memory used when creating a reference to this instance. e.g. via byref(obj)- Returns:
- The reference memory for this object

traverse
Description copied from interface:Traverseproc
Traverses all directly containedPyObject
s. Like in CPython,arg
must be passed unmodified tovisit
as its second parameter. IfVisitproc.visit(PyObject, Object)
returns nonzero, this return value must be returned immediately by traverse.Visitproc.visit(PyObject, Object)
must not be called with anull
PyObject-argument.- Specified by:
traverse
in interfaceTraverseproc
-
refersDirectlyTo
Description copied from interface:Traverseproc
Optional operation. Should only be implemented if it is more efficient than callingTraverseproc.traverse(Visitproc, Object)
with a visitproc that just watches out forob
. Must returnfalse
ifob
isnull
.- Specified by:
refersDirectlyTo
