setPreSaveFcn

Class: slreq.ReqSet
Namespace: slreq

Assign PreSaveFcn callback script

Since R2022a

Syntax

setPreSaveFcn(rs,callbackScript)


Description

setPreSaveFcn(rs,callbackScript) assigns the script specified by callbackScript as the PreSaveFcn callback script for the requirement set rs.

Input Arguments

rs — Requirement set

slreq.ReqSet object

Requirement set, specified as an slreq.ReqSet object.

callbackScript — Name of script to register

string scalar | character vector

Name of the script to register as the PreSaveFcn callback for the requirement set, specified as a string scalar or character vector.

Examples

Get and Set PreSaveFcn Callback

This example shows how to get and set the PreSaveFcn callback for a requirement set.

Add the current folder to the path.

addpath(pwd)

Open the ShortestPath project that contains an algorithm to calculate the shortest path between two nodes on a graph. For more information, see Verify a MATLAB Algorithm by Using Requirements-Based Tests.

openProject("ShortestPath");

Open the shortest_path_tests_reqs requirement set. The requirement set contains test requirements that describe the functional behavior that must be tested by a test case in order to verify the shortest_path algorithm in the project.

testReqs = slreq.open("shortest_path_tests_reqs");

Register the preSaveTestReqs script as the PreSaveFcn callback.

setPreSaveFcn(testReqs,"preSaveTestReqs");

Confirm that the preSaveTestReqs script is the PreSaveFcn callback for the shortest_path_tests_reqs requirement set.

callbackScript = getPreSaveFcn(testReqs)

callbackScript = 
'preSaveTestReqs'

Save the shortest_path_tests_reqs requirement set to execute the callback.

save(testReqs);

The preSaveTestReqs script saves the current Requirements Editor view settings to a MAT-file called myViewSettings.mat.

type preSaveTestReqs.m

slreq.exportViewSettings("myViewSettings.mat");
