RenumInfo::RenumExpression

Updates an expression when editing the flow in a model (inserting or deleting a processing unit)

int RenumExpression(
   ProcUnit     *ptrProcUnit,
   int  modelNo
);

Parameters

*ptrProcUnit	Pointer to processing unit information
modelNo	Model (expression) number to be converted

Return Value

Returns 0 when the expression is successfully converted.

Otherwise returns a non-zero value.

Description

Updates the specified expression when a processing unit is added, deleted, or moved.

For example, when the next expression is set to "U2.X+U3.Y+10", if you delete the unit 1 and execute this method, the expression is changed to "U1.X+U2.Y+10". Similarly, when it is set to "U2.X+U3.Y+10", if you delete the unit 2 and execute this method, the expression is changed to "#ERR+U2.Y+10".

Example

    int Sample::RenumProc(ProcUnit *ptrProcUnit, RenumInfo *ptrRenumInfo)
    {

        // Update expressions

        for (int modelNo = 0; modelNo < 8; modelNo++) {
            ptrRenumInfo->RenumExpression(ptrProcUnit, modelNo);
        }
    }
