PreOp
=====

.. py:class:: PreOp(expression)
   :canonical: ansys.scade.apitools.expr.access.PreOp



Bases: :py:obj:`CallExpression`


   Provides the previous value of flows.

   The format is ``pre <flow>, ..., <flow>``.

   See the :ref:`pre_op <ex__pre_op>` example.

   :Parameters:

       **expression**
           Call expression to wrap.









   .. rubric:: Notes

   The design differs slightly from the meta-model. Because the input
   must be a group of flows, the :class:`~PreOp` class does not inherit
   from the :class:`~FlowOp` class. It exposes directly the lists of flows instead of
   having a flow that is an instance of a :class:`~ListExpression` class.
