Examples

Create and Apply View to Requirements Editor

This example shows how to create a view and apply it to the Requirements Editor and Requirements Perspective.

Open the myAddRequirements requirement set, which contains requirements with Type set to Functional.

rs = slreq.open("myAddRequirements");

Create a view with the name NewView.

myView = slreq.View.create("NewView")

myView = 
  View with properties:

          Name: 'NewView'
     ReqFilter: ''
    LinkFilter: ''
          Host: ''

Set the requirement filter to only display requirements that have Type set to Container.

myView.ReqFilter = "{'ReqType','Container'};"

myView = 
  View with properties:

          Name: 'NewView'
     ReqFilter: '{'ReqType','Container'};'
    LinkFilter: ''
          Host: ''

Check if the view is valid.

tf = isValid(myView)

tf = logical
   1

Apply the view to the Requirements Editor and Requirements Perspective.

activate(myView)

Confirm that the active view is NewView.

appliedView = slreq.View.getActiveView

appliedView = 
  View with properties:

          Name: 'NewView'
     ReqFilter: '{'ReqType','Container'};'
    LinkFilter: ''
          Host: ''

The myAddRequirements requirement set does not contain any requirements with Type set to Container, so all of the requirements are filtered out.
