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.

Create View and Store in Requirement Set

This example shows how to create a view and store it in a requirement set.

Load and open the myAddRequirements requirement set.

rs = slreq.open("myAddRequirements");

Create a view and store it in the requirement set.

myView = slreq.View.create("NewView","myAddRequirements");

Create Copy of View

This example shows how to create a copy of an existing view.

Load the myAddRequirements requirement set.

rs = slreq.open("myAddRequirements");

Load the view settings file ViewFile2.mat, which contains a view stored in the preferences folder.

slreq.importViewSettings("ViewFile2")

Get the existing views from the view settings file.

views = slreq.View.getViews

views=1×2 View array with properties:
    Name
    ReqFilter
    LinkFilter
    Host

Assign the second view in the array to a variable.

viewToCopy = views(2)

viewToCopy = 
  View with properties:

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

Create a copy of the view and store it in the requirement set.

copiedView = slreq.View.create("CopiedView", ...
    "myAddRequirements",viewToCopy);
