Constructor Details
- PyReversedIterator
  
  public PyReversedIterator(PyObject seq)
  
  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__
  
  public PyObject __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 class PyIterator
- traverse
  
  public int traverse(Visitproc visit, Object arg)
  
  Description copied from interface: Traverseproc
  
  Traverses all directly contained PyObjects. Like in CPython, arg must be passed unmodified to visit as its second parameter. If Visitproc.visit(PyObject, Object) returns nonzero, this return value must be returned immediately by traverse. Visitproc.visit(PyObject, Object) must not be called with a null PyObject-argument.
  
  Specified by:
  
  traverse in interface Traverseproc
  
  Overrides:
  
  traverse in class PyIterator
- refersDirectlyTo
  
  public boolean refersDirectlyTo(PyObject ob)
  
  Description copied from interface: Traverseproc
  
  Optional operation. Should only be implemented if it is more efficient than calling Traverseproc.traverse(Visitproc, Object) with a visitproc that just watches out for ob. Must return false if ob is null.
  
  Specified by:
  
  refersDirectlyTo in interface Traverseproc
  
  Overrides:
  
  refersDirectlyTo in class PyIterator
