Package: slreq

Move referenced requirement up in hierarchy


tf = moveUp(ref)


tf = moveUp(ref) moves the referenced requirement ref up one spot in the hierarchy, and returns 1 if the move executes without error. The referenced requirement ref cannot be moved to a new level in the hierarchy.


You can use this method only in the PostImportFcn callback.

Input Arguments

Referenced requirement, specified as a slreq.Reference object.

Output Arguments

Move success status, returned as a 1 or 0 of data type logical.

This example shows how to move an imported referenced requirement up and down in the hierarchy in the PostImportFcn callback.

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 movePostImport as the PostImportFcn callback to use during import. Return a handle to the requirement set.

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

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. The script then finds the referenced requirement that has Summary set to Requirement 3 and moves it up. It also finds the referenced requirement that has Summary set to Requirement 1 and moves it down.

type movePostImport.m
topRef = slreq.getCurrentObject;
rs = reqSet(topRef);
ref1 = find(rs,Type="Reference",Summary="Requirement 3");
tf1 = moveUp(ref1);
ref2 = find(rs,Type="Reference",Summary="Requirement 1");
tf2 = moveDown(ref2);
