setPreImportFcn
Class: slreq.Reference
Namespace: slreq
Syntax
setPreImportFcn(topRef,callbackScript)
Description
setPreImportFcn(
assigns the script specified by topRef
,callbackScript
)callbackScript
as the
PreImportFcn
callback script for the Import node
topRef
.
Input Arguments
topRef
— Import node
slreq.Reference
object
Import node, specified as an slreq.Reference
object.
callbackScript
— Name of script to register
string scalar | character vector
Name of the script to register as the PreImportFcn
callback for
the Import node, specified as a string scalar or character vector.
Examples
Use PreImportFcn
Callback During Import
This example shows how to assign a script as the PreImportFcn
callback for an Import node. You get the contents of the PreImportFcn
callback for an Import node and register a different script as the PreImportFcn
callback after you import the requirements.
Import the Requirements
Use slreq.import
to import the ReqIF™ file mySpec.reqif
into Requirements Toolbox™. Name the imported requirement set myReqSet
and register the script myPreImportScript
as the PreImportFcn
callback to use during import. Return a handle to the requirement set.
[~,~,rs] = slreq.import("mySpec.reqif",ReqSet="myReqSet",preImportFcn="myPreImportScript");
The script myPreImportScript
uses slreq.getCurrentImportOptions
to get the import options, then specifies the attribute mapping file to use during import.
type myPreImportScript.m
importOptions = slreq.getCurrentImportOptions; importOptions.MappingFile = "myMappingFile.xml";
The mapping file myMappingFile.xml
uses a generic mapping.
Get the custom ID for the requirement with Index
set to 1
.
req1 = find(rs,Index="1");
cID = req1.CustomId
cID = 0x0 empty char array
The generic mapping does not map the ReqIF attribute ID
to the Requirement Toolbox attribute Custom ID
. Instead, ID
imports as a custom attribute. Get the value for the ID
custom attribute for Requirement 1
.
cID = getAttribute(req1,"ID")
cID = 'A1'
Get and Set the PreImportFcn
Callback Script
Get a handle to the Import node, then register the script myPreImportScrip2
as the PreImportFcn
callback. Confirm that the registered callback was changed.
topRef = children(rs);
setPreImportFcn(topRef,"myPreImportScript2")
newCallback = getPreImportFcn(topRef)
newCallback = 'myPreImportScript2'
The script myPreImportScript2
uses slreq.getCurrentImportOptions
to get the import options, then specifies the attribute mapping file to use during import.
type myPreImportScript2.m
importOptions = slreq.getCurrentImportOptions; importOptions.MappingFile = "myMappingFile2.xml";
The mapping file myMappingFile2.xml
maps these attributes from the ReqIF™ file to these properties in Requirements Toolbox™:
ReqSum
toSummary
Desc
toDescription
ID
toCustom ID
Update the requirement set. The PreImportFcn
callback script also executes when you update the requirement set.
updateReferences(rs,topRef);
Get the custom ID for the requirement with Index
set to 1
.
req1 = find(rs,Index="1");
cID = req1.CustomId
cID = 'A1'
