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

• next

  public PyObject next()

  Description copied from class: PyIterator

  The exposed next method. Note that exposed derivable subclasses of PyIterator should override next to call doNext(custom___iternext__), as __iternext__ is overridden by the Derived classes.

  Overrides:

  next in class PyIterator

  Returns:

  a PyObject result

• 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
