Accessing Engineering Specification Resources through Business Logic

In the context of a business logic, you can access Engineering Specification resources thanks to a resource finder. The following task describes the procedure to add the required information in the Business Logic.

  1. Create a resource finder. 
    /* Create the resource finder */
pEnsEngSpecResourceFinder = new("EnsEngSpecResourceFinder","EnsEngSpecResourceFinder1",NULL)
if (pEnsEngSpecResourceFinder <> NULL)
  2. Add the required information to find the resources. 
    {
   /* Init the information on the resource finder */
   pEnsEngSpecResourceFinder->SetAttributeString("ApplicationName","CATPiping")
   pEnsEngSpecResourceFinder->SetAttributeString("ApplicativeOperationName","_MultiSpec")
   pEnsEngSpecResourceFinder->SetAttributeString ("SearchedResourceKind","MinimumTangentLength")
      
   /* Set a resource filtering expression based on PLM attributes */
   pEnsCondition1 = new("EnsCondition","ExpCondition1",NULL)
   pEnsCondition2 = new("EnsCondition","ExpCondition2",NULL)
   if ( (pEnsCondition1 <> NULL) AND (pEnsCondition2 <> NULL) )
   {
      pEnsCondition1->SetAttributeString("ParameterName","V_sec_level")
      /* Warning : only operator “==” accepted */
      pEnsCondition1->SetAttributeString("Operator","==")
      pEnsCondition1->SetAttributeInteger("ParameterValue",-1)
      EnsConditions->Append(pEnsCondition1)

      pEnsCondition2->SetAttributeString("ParameterName","organization")
      /* Warning : only operator “==” accepted */
      pEnsCondition2->SetAttributeString("Operator","==")
      pEnsCondition2->SetAttributeString("ParameterValue","MyCompany")
      EnsConditions->Append(pEnsCondition2)

      pEnsExpression = new("EnsExpression","EnsExpression1",NULL)
      if (pEnsExpression <> NULL)
      {
	 pEnsExpression->SetAttributeObject("ListOfEnsConditions",EnsConditions)
        pEnsEngSpecResourceFinder->SetAttributeObject   ("EnsExpressionToFilterSearchedResource",pEnsExpression)  	  
      } 
   }   

   /* Set applicative entities */
   /* Remark : ens specification object is used just to check that the SetAtttributeObject works correctly on the EnsEngSpecResourceFinder : in a real case, these entities are not the specs, but other current entities depending on the current operation */

   EnsApplicativeEntitiesKeys->Append("EnsSpecification1") 
   EnsApplicativeEntities->Append(pEnsSpecObj)  
   pEnsEngSpecResourceFinder->SetAttributeObject ("ListOfCurApplicativeEntitiesKeys",EnsApplicativeEntitiesKeys)
   pEnsEngSpecResourceFinder->SetAttributeObject ("ListOfCurApplicativeEntities",EnsApplicativeEntities)

  /* Set the initial ens specifications: customer additional ones (if any) will be    automatically added internally and must not be set */
  pEnsEngSpecResourceFinder->SetAttributeObject ("ListOfCurEnsSpecifications",EnsSpecs)
  3. Get the result type.

    Note: The result type can be a table or a filter.

    If the result type is a table, the exact result type is obtained through a call to GetEnsTechnoTableResultType. 

    /* Get the type the created ens techno table for result must be a sort of */
  pEnsEngSpecResourceFinder->GetEnsTechnoTableResultType(sEnsTechnoTableResultRequiredType)

    If the result type is a filter, the exact result type is obtained through a call to GetEnsFilterResultType. 

    /* Get the type the created ens filter for result must be a sort of */
  pEnsEngSpecResourceFinder->GetEnsFilterResultType(sEnsFilterResultRequiredType)
  4. Create a result object with the object type you obtained at step 3. 
    /* Initialize the ens techno table result */
  pEnsTechnoTableResult = new(sEnsTechnoTableResultRequiredType, "EnsTechnoTableResult1", NULL)   
  if (pEnsTechnoTableResult <> NULL)
  5. Run the resource finder to fill the result object created at step 4. 
         /* Run the resource finder for resource search: case ens technological tables */
     pEnsEngSpecResourceFinder->GetEnsTechnoTableResult(pEnsTechnoTableResult)

    The result is inserted in the created table or filter. The searched resource is this object which can be accessed through knowledge services.

    Note: You can add a filter on the resource finder in the form of a filtering expression. An expression is build with conditions and a condition is a parameter name, an operation and a value, for example material=inox. You need to create first the conditions with their three elements and then you create the expression in which you list the conditions.
