    - #### PyBytecode

          public PyBytecode(int argcount,
                    int nlocals,
                    int stacksize,

                    String[] cellvars,
                    String[] freevars)

  - ### Method Detail

    - #### _allDebug

          public static void _allDebug(boolean setting)

    - #### _debug

          public PyObject _debug(int maxCount)

    - #### __dir__

          public PyObject __dir__()

      Description copied from class: `PyObject`
      Equivalent to the standard Python __dir__ method.
      Overrides:
        `__dir__` in class `PyObject`
      Returns:
        a list of names defined by this object.

    - #### __setattr__

          public void __setattr__(String name,
                         PyObject value)

      Description copied from class: `PyObject`
      A variant of the __setattr__ method which accepts a String as the key. This String must be interned.
      Overrides:
        `__setattr__` in class `PyObject`
      Parameters:
        `name` - the name whose value will be set - must be an interned string .
        `value` - the value to set this name to
      See Also:
        `PyObject.__setattr__(PyString, PyObject)`

    - #### __delattr__

          public void __delattr__(String name)

      Description copied from class: `PyObject`
      A variant of the __delattr__ method which accepts a String as the key. This String must be interned. By default, this will call `__delattr__(PyString name)` with the appropriate args. The only reason to override this method is for performance.
      Overrides:
        `__delattr__` in class `PyObject`
      Parameters:
        `name` - the name which will be removed - must be an interned string .
      See Also:
        `PyObject.__delattr__(PyString)`

    - #### __findattr_ex__

          public PyObject __findattr_ex__(String name)

      Description copied from class: `PyObject`
      Attribute lookup hook. If the attribute is not found, null may be returned or a Py.AttributeError can be thrown, whatever is more correct, efficient and/or convenient for the implementing class. Client code should use `PyObject.__getattr__(String)` or `PyObject.__findattr__(String)`. Both methods have a clear policy for failed lookups.
      Overrides:
        `__findattr_ex__` in class `PyObject`
      Returns:
        The looked up value. May return null if the attribute is not found

    - #### traverse

          public int traverse(Visitproc visit,
                     Object arg)

      Description copied from interface: `Traverseproc`
      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.
      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`
