public java.lang.String getName()

public PyObject throw$(PyObject type,
                       PyObject value,
                       PyObject tb)

close

public PyObject close()

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

__iter__

public PyObject __iter__()

Description copied from class: PyObject

Return an iterator that is used to iterate the element of this sequence. From version 2.2, this method is the primary protocol for looping over sequences.

If a PyObject subclass should support iteration based in the __finditem__() method, it must supply an implementation of __iter__() like this:

 public PyObject __iter__() {
     return new PySequenceIter(this);
 }
 

When iterating over a python sequence from java code, it should be done with code like this:

 for (PyObject item : seq.asIterable()) {
     // Do something with item
 }
 

Overrides:

__iter__ in class PyIterator

__del_builtin__

public void __del_builtin__()

Description copied from interface: FinalizableBuiltin

FinalizableBuiltin.__del_builtin__() is the built-in's own finalizer, while FinalizablePyObjectDerived.__del_derived__() refers to an instance's in-dict __del__. A FinalizeTrigger calls FinalizablePyObjectDerived.__del_derived__() first and - if existent - FinalizableBuiltin.__del_builtin__() after that. A plain FinalizablePyObject.__del__() would behave as overridden by FinalizablePyObjectDerived.__del_derived__(), i.e. won't be called if the type implements FinalizablePyObjectDerived, while FinalizableBuiltin.__del_builtin__() is called in any case.

Specified by:

__del_builtin__ in interface FinalizableBuiltin

__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

__iternext__

public PyObject __iternext__(ThreadState state)

toString

public java.lang.String toString()

Overrides:

toString in class PyObject

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
