Examples

Add a Child Requirement Under a Requirement

This example shows how to add a child requirement under a requirement.

Load the requirement set myReqSet, which does not contain any requirements.

rs = slreq.load("myReqSet");

Use the add method to add a top-level requirement to the requirement set.

req = add(rs);

Use the add method to add a child requirement under the requirement.

newReq = add(req)

newReq = 
  Requirement with properties:

            Type: 'Functional'
              Id: '#3'
         Summary: ''
     Description: ''
        Keywords: {}
       Rationale: ''

        Comments: [0×0 struct]
           Index: '1.1'

Get the value of the Index property for the new requirement.

idx = newReq.Index

idx = 
'1.1'

The value indicates that the new requirement is a child requirement of the original requirement.

Cleanup

Discard the requirement set without saving.

discard(rs);

Tips

• To add a top-level requirement to a requirement set, use the add method of slreq.ReqSet. To add a referenced requirement as a child of another referenced requirement, use the add method of slreq.Reference. To add a justification as a child of another justification, use the add method of slreq.Justification.
