Convert link source or destination information from structure to model object type


ot = slreq.structToObj(linkinfo) converts the source or destination link information in linkinfo to ot the appropriate object type. Examples of object types include Simulink® blocks and Simulink Test™ test cases.

This example shows how to get the structure containing unique requirement source and destination information, then convert the structure information to the specific source and destination model entity.

Load Model, Requirement Set, and Links

rq = slreq.load('original_thrust_reverser_requirements.slreqx');
lk = slreq.load('reqs_validation_property_proving_original_model.slmx');

For a LinkSet

Get sources from a LinkSet, get a single source, and convert the structure to the model entity.

lksrcs = sources(lk);
lksrc1 = lksrcs(1)
lksrc1 = struct with fields:
      domain: 'linktype_rmi_simulink'
    artifact: '/tmp/Bdoc20a_1326390_25025/tp0a96d147/slrequirements-ex49678366/reqs_validation_property_proving_original_model.slx'
          id: ':16:151'

ot1 = slreq.structToObj(lksrc1)
ot1 =

For a Link

Get a link from the link set, and get the source and destination for that link. Convert the source and destination structure to the model entity.

sl = getLinks(lk);
sl2 = sl(2);
sl2src = source(sl2)
sl2src = struct with fields:
      domain: 'linktype_rmi_simulink'
    artifact: '/tmp/Bdoc20a_1326390_25025/tp0a96d147/slrequirements-ex49678366/reqs_validation_property_proving_original_model.slx'
          id: ':16:31'

sl2dest = destination(sl2)
sl2dest = struct with fields:

ot2s = slreq.structToObj(sl2src)

linkinfo contains source artifact and unique identification information for particular links, as returned by

Example: struct with fields

Data Types: struct

Output Arguments
