How to invoke MOFSCRIPT from java code.. [message #375594] Thu, 02 November 2006 09:14 Go to next message

Hi! I have several MOFSCRIPT transformations but I would like to invoke
them directly form my Java code, instead of using MOFSCRIPT interface.
Hence, the user of my plug-in would be able to accomplish a
transformation by means of right-click or just a button-click.

Does anyone know how to accomplish this? Any hint? I've seen another
post with the same problem but it does not have any reply.

Thanks in advance,
Gabriel Merin

Hi,

This is documented by an example in the latest MOFScript documentation
(see http://www.eclipse.org/gmt/mofscript/doc/ or
http://www.modelbased.net/mofscript/docs/MOFScript-User-Guid e.pdf).

Example code for parsing and executing is given below:

ParserUtil parserUtil = new ParserUtil();
ExecutionManager execMgr = ExecutionManager.getExecutionManager();
//
// The parserutil parses and sets the input transformation model
// for the execution manager.
//
File f = new File ("EcoreTest.m2t");
MOFScriptSpecification spec = parserUtil.parse(f, true);
// check for errors:
int errorCount = ParserUtil.getModelChecker().getErrorCount();
Iterator errorIt = ParserUtil.getModelChecker().getErrors(); // Iterator
of MofScriptParseError objects

System.out.println ("Parsing result: " + errorCount + " errors");
if (errorCount > 0) {

for (;errorIt.hasNext();) {
MofScriptParseError parseError = (MofScriptParseError) errorIt.next();
System.out.println("\t \t: Error: " + parseError.toString());
}
return;
}



// load source model
XMIResourceFactoryImpl _xmiFac = new XMIResourceFactoryImpl();
EObject sourceModel = null;
File sourceModelFile = new File ("SM.ecore");
ResourceSet rSet = new ResourceSetImpl ();
rSet.getResourceFactoryRegistry().getExtensionToFactoryMap() .put( "*",
_xmiFac);
URI uri = URI.createFileURI(sourceModelFile.getAbsolutePath());
Resource resource = rSet.getResource(uri, true);

if (resource != null) {
if (resource.getContents().size() > 0) {
sourceModel = (EObject) resource.getContents().get(0);
}
}

// set the source model for the exeution manager
execMgr.addSourceModel(sourceModel);
// sets the root output directory, if any is desired (e.g. "c:/temp")
execMgr.setRootDirectory("");
// if true, files are not generated to the file systsm, but populated
into a filemodel
// which can be fetched afterwards. Value false will result in standard
file generation
execMgr.setUseFileModel(false);
// Turns on/off system logging
execMgr.setUseLog(false);
// Adds an output listener for the transformation execution.
execMgr.getExecutionStack().addOutputMessageListener(this);
try {

execMgr.executeTransformation();
} catch (MofScriptExecutionException mex) {
mex.printStackTrace();
}

Hello,
I am trying to do the same, but I have a main trnasformation which imports
several transformations. When I run the java file (using File f = new File
( main.m2t");) I get several errors, such as:

Error: MTTParseError: Cannot find import: second.m2t, line: 7, column: 7
.....
If I run the main transformation using the MOFSCRIPT interface it works, but
not if I invoke them directly from my java code.
Any hint?

Thanks in advance
