Open Live Script

This example shows how to assign a script as the PostImportFcn callback for an Import node. You get the contents of the PostImportFcn callback for an Import node and register a different script after you import the requirements.

Import the Requirements

Use slreq.import to import the ReqIF file mySpec.reqif into Requirements Toolbox™. Name the imported requirement set myReqSet, register the script myPreImportScript2 as the PreImportFcn, and register the script myPostImportScript as the PostImportFcn callback. Return a handle to the requirement set.

[~,~,rs] = slreq.import("mySpec.reqif",ReqSet= ...
    "myReqSet",preImportFcn="myPreImportScript2", ...
    postImportFcn="myPostImportScript");

The script myPreImportScript2 uses slreq.getCurrentImportOptions to get the import options, then specifies the attribute mapping file to use during import.

type myPreImportScript2.m
importOptions = slreq.getCurrentImportOptions;
importOptions.MappingFile = "myMappingFile2.xml";

The mapping file myMappingFile2.xml maps these attributes from the ReqIF™ file to these properties in Requirements Toolbox™:

  • ReqSum to Summary

  • Desc to Description

  • ID to Custom ID

The script myPostImportScript uses slreq.getCurrentObject to get a handle to the Import node, gets the requirement set that the Import node belongs to, and then finds requirements that have the summary Requirement 1 and Requirement 2. Then, the script moves Requirement 2 under Requirement 1.

type myPostImportScript.m
topRef = slreq.getCurrentObject;
rsScratch = reqSet(topRef);
ref = find(rsScratch,Type="Reference",Summary="Requirement 2");
parentRef = find(rsScratch,Type="Reference",Summary="Requirement 1");
parentID = parentRef.SID;
setParent(ref,parentID);

Confirm that Requirement 2 is a child of Requirement 1.

req1 = find(rs,Summary="Requirement 1");
req2 = children(req1);
reqSummary = req2.Summary
reqSummary = 
'Requirement 2'

Get and Set the PostImportFcn Callback

Get a handle to the Import node, then register the script myPostImportScrip2 as the PostImportFcn callback. Confirm that the contents of the callback changed.

topRef = children(rs);
setPostImportFcn(topRef,"myPostImportScript2")
newCallback = getPostImportFcn(topRef)
newCallback = 
'myPostImportScript2'

The myPostImportScript2 script moves Requirement 2 under Requirement 3.

type myPostImportScript2.m
topRef = slreq.getCurrentObject;
rsSc = reqSet(topRef);
ref = find(rsSc,Type="Reference",Summary="Requirement 2");
parentRef = find(rsSc,Type="Reference",Summary="Requirement 3");
parentID = parentRef.SID;
setParent(ref,parentID);

Update the requirement set. The PostImportFcn callback executes after you update the requirement set.

updateReferences(rs,topRef);

Confirm that Requirement 2 is a child of Requirement 3.

req3 = find(rs,Summary="Requirement 3");
req2 = children(req3);
reqSummary = req2.Summary
reqSummary = 
'Requirement 2'
