@ExposedType
name:classmethod
doc:classmethod(function) -> method Convert a function to be a class method. A class method receives the class as implicit first argument, just like an instance method receives the instance. To declare a class method, use this idiom: class C: def f(cls, arg1, arg2, ...): ... f = classmethod(f) It can be called either on the class (e.g. C.f()) or on an instance (e.g. C().f()). The instance is ignored except for its class. If a class method is called for a derived class, the derived class object is passed as the implied first argument. Class methods are different than C++ or Java static methods. If you want those, see the staticmethod builtin.

Get descriptor for this PyObject.

Parameters
obj:PyObject

- the instance accessing this descriptor. Can be null if this is being accessed by a type.

type:PyObject

- the type accessing this descriptor. Will be null if obj exists as obj is of the type accessing the descriptor.

Returns:PyObject

- the object defined for this descriptor for the given obj and type.

public boolean refersDirectlyTo(PyObject ob)

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)

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.
