public PyObject next()

Overrides org.python.core.PyIterator.next.

Doc from org.python.core.PyIterator.next.

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.

Returns:PyObject

a PyObject result

public boolean refersDirectlyTo(PyObject ob)

Overrides org.python.core.PyIterator.refersDirectlyTo.

Implements org.python.core.Traverseproc.refersDirectlyTo.

Doc from org.python.core.Traverseproc.refersDirectlyTo.

Optional operation. Should only be implemented if it is more efficient than calling traverse(Visitproc, Object) with a visitproc that just watches out for ob. Must return false if ob is null.

traverseback to summary
public int traverse(Visitproc visit, Object arg)

Overrides org.python.core.PyIterator.traverse.

Implements org.python.core.Traverseproc.traverse.

Doc from org.python.core.Traverseproc.traverse.

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.
