PyReversedIterator

back to summary

public PyReversedIterator(PyObject seq)

Creates an iterator that first yields the item at __len__ - 1 on seq and returns the objects in descending order from there down to 0.

Parameters

seq:PyObject: - an object that supports __getitem__ and __len__

Method Detail

__iternext__	back to summary
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.

__iternext__

back to summary

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.

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`.

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.

Traverses all directly contained `PyObject`s. 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.

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.
