  • Method Details

    • property___init__

      public void property___init__(PyObject[] args, String[] keywords)

    • __call__

      public PyObject __call__(PyObject arg1, PyObject[] args, String[] keywords)
      Description copied from class: PyObject
      A variant of the __call__ method with one extra initial argument. This variant is used to allow method invocations to be performed efficiently. The default behavior is to invoke __call__(args, keywords) with the appropriate arguments. The only reason to override this function would be for improved performance.
      Overrides:
      __call__ in class PyObject
      Parameters:
      arg1 - the first argument to the function.
      args - the last arguments to the function (including keyword arguments).
      keywords - the keywords used for all keyword arguments.

    • __get__

      public PyObject __get__(PyObject obj, PyObject type)
      Description copied from class: PyObject
      Get descriptor for this PyObject.
      Overrides:
      __get__ in class PyObject
      Parameters:
      obj - - the instance accessing this descriptor. Can be null if this is being accessed by a type.
      type - - the type accessing this descriptor. Will be null if obj exists as obj is of the type accessing the descriptor.
      Returns:
      - the object defined for this descriptor for the given obj and type.

    • __set__

      public void __set__(PyObject obj, PyObject value)
      Overrides:
      __set__ in class PyObject

    • __delete__

      public void __delete__(PyObject obj)
      Overrides:
      __delete__ in class PyObject

    • traverse

      public int traverse(Visitproc visit, 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

    • 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
