hi to all
i have some problemens using check in XPand
for now i have done this:

Resource resource;
//...load resource

OutputImpl output = new OutputImpl();
//...

ProtectedRegionResolverImpl prs = new ProtectedRegionResolverImpl();
//...

UML2MetaModel mm = new UML2MetaModel();

Map<String,Variable> globalVarsMap = new HashMap<String,Variable>();
//...
XpandExecutionContextImpl execCtx = new XpandExecutionContextImpl(output, prs,
globalVarsMap, null, null);
execCtx.registerMetaModel(mm);

//checkcomponents
CheckComponent c = new CheckComponent();
c.addMetaModel(mm);
c.addCheckFile("templateMiddle::javacheck");
WorkflowContextImpl ctx = new WorkflowContextImpl();
ctx.put("", resource.getContents().get(0));
c.invoke(ctx);

//für primtive Types etc...
new Setup().setStandardUML2Setup(true);

XpandFacade facade = XpandFacade.create(execCtx);
facade.evaluate("templateMiddle::Template::main", resource.getContents().get(0));

i have added to the checkcomponent the metamodel and the checkFile. because i found no possibility to set the checkcomponent in the executionContext, i guess i have to use the invoke method of the checkcomponent. but this method expects a WorkFlowContext Object. but i'm not sure what i have put in this workFlowObject. Maybe someone knows it?

greetings
stoehm

Hi,

you are right. it is impossible to get the XpandFacade running Checks.
the thing is called XpandFacade and not WorkflowFacade. Thus it facades Xpand and not a Workflow nor Check or Xtend.
But (what a miracle) there are also a CheckFacade, a XtendFacade and a WorkflowRunner

hi christian
thanks for your reply. sorry, i have not think of that, because the name xpand is often use for the whole framework, instead only for the templates

hi
trying to use CheckFacade to check the model, i have some problems:
i used

CheckFacade.checkAll(String checkFile, Collection<?> toCheck, ExecutionContext ctx, Issues issues)

the execution context and the checkFile is no problem, but i'am not sure what the toCheck Collection is needed. null is not allowed and debugging does not really help. i just figure out, that for each object of the collection a type check is done.
so a hint what the parameters exactly means is very helpfull for me
(btw: i wonder how the actual model is announced to the CheckFacade )

greetings stoehm

The toCheck collection is the collection of objects to perform the validation on.
I have added javadocs now.

/**
* Invokes Check validation on a set of objects.
* @param checkFile Qualified name of the check file (qualified with '::')
* @param in The InputStream to use to load checkFile
* @param toCheck A collection of objects to perform the validation on
* @param ctx Execution context to use for evaluating the Check rules
* @param issues Issues instance to collect detected problems in
* @param warnIfNothingChecked When set a warning will be raised if no validation rule was executed

hi karsten
thanks for your reply!
i'm sorry, i'm still not sure about the toCheck Parameter! Is this a collection where i can put my models into? normally i have only one model!

i set in the parameter the root of my model like i did in xpandfacade but it does not work!

this it what i tried:

...//put the uml-model in a resource

ArrayList<Object> al= new ArrayList<Object>();
//put the root of the model in the arraylist
al.add(resource.getContents().get(0));
CheckFacade.checkAll("templateMiddle::javacheck", al, execCtx, null,false);

//here i put also the root in the parameterlist; and here it does work
XpandFacade facade = XpandFacade.create(execCtx);
facade.evaluate("templateMiddle::Template::main", resource.getContents().get(0));

so i'm still doing something wrong, any idea?

The collection should contain all the elements to check, so most likely the model itself and all of its contents, i.e. eAllContents

thanks a lot, now it works fine!
for everbody who is interested, the code is below

//...put the model in a resource

LinkedList<Object> ll = new LinkedList<Object>();
//copy the treeIterator from eAllContents into a linkedList
for(TreeIterator<EObject> iterator = resource.getContents().get(0).eAllContents(); iterator.hasNext();){
ll.add(iterator.next());
}

IssuesImpl issues =new IssuesImpl();
CheckFacade.checkAll("templateMiddle::javacheck",ll , execCtx, issues);

//print out all Errors that are detected
MWEDiagnostic[] errors = issues.getErrors();
for(int i=0;i<errors.length;i++){
System.out.println(errors[i].toString());
}

//print out all Warnings that are detected
MWEDiagnostic[] warnings = issues.getWarnings();
for(int i=0;i<warnings.length;i++){
System.out.println(warnings[i].toString());
}

//only evalute the xpandfacade when there are no errors
if(!issues.hasErrors()){
XpandFacade facade = XpandFacade.create(execCtx);
facade.evaluate("templateMiddle::Template::main", resource.getContents().get(0));
}
