@ExposedType
name:itertools.izip
base:PyObject
doc:izip(iter1 [,iter2 [...]]) --> izip object Return an izip object whose .next() method returns a tuple where the i-th element comes from the i-th iterable argument. The .next() method continues until the shortest iterable in the argument sequence is exhausted and then it raises StopIteration. Works like the zip() function but consumes less memory by returning an iterator instead of a list.

Optional operation.

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.

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

Create an iterator whose next() method returns a tuple where the i-th element comes from the i-th iterable argument. Continues until the shortest iterable is exhausted. (Code in this method is based on __builtin__.zip()).

public PyObject 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.

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.

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.
