      Description copied from class: PyObject
      Equivalent to the Jython __tojava__ method. Tries to coerce this object to an instance of the requested Java class. Returns the special object Py.NoConversion if this PyObject can not be converted to the desired Java class.
      Overrides:
      __tojava__ in class PyObject

      Overrides:
      __findattr__ in class PyObject
      Parameters:
      name - the name to lookup in this namespace must be an interned string .
      Returns:
      the value corresponding to name or null if name is not found

    • __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 .

      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

    • __call__

      public PyObject __call__(PyObject[] args, String[] keywords)
      Description copied from class: PyObject
      The basic method to override when implementing a callable object. The first len(args)-len(keywords) members of args[] are plain arguments. The last len(keywords) arguments are the values of the keyword arguments.
      Overrides:
      __call__ in class PyObject
      Parameters:
      args - all arguments to the function (including keyword arguments).
      keywords - the keywords used for all keyword arguments.
