__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 }
-
__finditem__
Description copied from class:PyObject
Very similar to the standard Python __getitem__ method. Instead of throwing a KeyError if the item isn't found, this just returns null. Classes that wish to implement __getitem__ should override this method instead (with the appropriate semantics.- Overrides:
__finditem__
in classPyObject
- Parameters:
key
- the key to lookup in this container- Returns:
- the value corresponding to key or null if key is not found
-
__len__
public int __len__()Description copied from class:PyObject
Equivalent to the standard Python __len__ method. Part of the mapping discipline. -

__str__
Description copied from class:PyObject
Equivalent to the standard Python __str__ method. The default implementation (inPyObject
) callsPyObject.__repr__()
, making it unnecessary to override__str__
in sub-classes ofPyObject
where both forms are the same. A common choice is to provide the same implementation to__str__
andtoString
, for consistency in the printed form of objects between Python and Java. -

traverse
Description copied from interface:Traverseproc
Traverses all directly containedPyObject
s. Like in CPython,arg
must be passed unmodified tovisit
as its second parameter. IfVisitproc.visit(PyObject, Object)
returns nonzero, this return value must be returned immediately by traverse.Visitproc.visit(PyObject, Object)
must not be called with anull
PyObject-argument.- Specified by:
traverse
in interfaceTraverseproc
-
refersDirectlyTo
Description copied from interface:Traverseproc
Optional operation. Should only be implemented if it is more efficient than callingTraverseproc.traverse(Visitproc, Object)
with a visitproc that just watches out forob
. Must returnfalse
ifob
isnull
.- Specified by:
refersDirectlyTo
