@abc.abstractmethod<EOL><INDENT>def implements_value_object_type(self, value_type):<DEDENT>
return<EOL>
Tests if the object supports the given ``Type``.

        This method should be checked before retrieving the object
        value.

        :param value_type: a type
        :type value_type: ``osid.type.Type``
        :return: ``true`` if the obect values associated with this parameter implement the given ``Type,``  ``false``
        otherwise
        :rtype: ``boolean``
        :raise: ``IllegalState`` -- ``get_value_syntax() != object``
        :raise: ``NullArgument`` -- ``value_type`` is ``null``
