PyReversedIterator
Creates an iterator that first yields the item at __len__ - 1 on seq and returns the objects in descending order from there down to 0.- Parameters:
seq
- - an object that supports __getitem__ and __len__
-
-
Method Details
-
__iternext__
Description copied from class:PyObject
Return the next element of the sequence that this is an iterator for. Returns null when the end of the sequence is reached.- Specified by:
__iternext__
in classPyIterator
-
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
- Overrides:
traverse
in classPyIterator
-
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
in interfaceTraverseproc
