Method Detail

__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,
                    java.lang.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
