Method Summary

Modifier and TypeMethod and Description
public PyObject
__iternext__()

Implements abstract org.python.core.PyIterator.__iternext__.

Return the next element of the sequence that this is an iterator for.

pack-priv final void
groupby___init__(PyObject[] args, String[] kwds)

Creates an iterator that returns the items of the iterable for which predicate(item) is true.

groupby___init__(final PyObject iterable, final PyObject keyfunc)

public PyObject
next()

Overrides org.python.core.PyIterator.next.

The exposed next method.

public boolean
refersDirectlyTo(PyObject ob)

Overrides org.python.core.PyIterator.refersDirectlyTo.

Implements org.python.core.Traverseproc.refersDirectlyTo.

Optional operation.

public int
traverse(Visitproc visit, Object arg)

Overrides org.python.core.PyIterator.traverse.

Implements org.python.core.Traverseproc.traverse.

Traverses all directly contained PyObjects.

public PyObject __iternext__()

Implements abstract org.python.core.PyIterator.__iternext__.

Doc from org.python.core.PyObject.__iternext__.

Return the next element of the sequence that this is an iterator for. Returns null when the end of the sequence is reached.

groupby___init__back to summary
pack-priv final void groupby___init__(PyObject[] args, String[] kwds)

Creates an iterator that returns the items of the iterable for which predicate(item) is true. If predicate is null (None) return the items that are true.

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.
