PreOp#

class ansys.scade.apitools.expr.access.PreOp(expression: scade.model.suite.ExprCall)#

Bases: CallExpression

Provides the previous value of flows.

The format is pre , ..., .

See the pre_op example.

Notes#

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

Parameters#

expression :

Call expression to wrap.

Initialize the instance from the Scade expression.
