Re: [geclipse-dev] parsing a string into a model

["Katarzyna Bylec" <katis@xxxxxxxxxxxxx>]

Hi Harald,

If it is possible for you to write this String into a regular Java file -  
this can be done. Here's the method from new JSDLJobDescription (IResource  
independent) class (not committed yet). It takes java.io.file and reads  
EMF model from it:

public void loadModel( final File file ) throws IOWrappedException {
    if( file.length() != 0 ) {
      //STEP 1: creation of EMF resource needed to load the EMF model
      String filePath = file.getAbsolutePath();
      org.eclipse.emf.common.util.URI uri =  
org.eclipse.emf.common.util.URI.createFileURI( filePath );
      ResourceSet resourceSet = new ResourceSetImpl();
      Resource resourceA = resourceSet.createResource( uri );
      //STEP 2: setting EMF model options
      XMLMapImpl xmlmap = new XMLMapImpl();
      xmlmap.setNoNamespacePackage( JsdlPackage.eINSTANCE );
      Map<String, Object> options = new HashMap<String, Object>();
      options.put( XMLResource.OPTION_XML_MAP, xmlmap );
      options.put( XMLResource.OPTION_ENCODING, "UTF8" ); //$NON-NLS-1$
      try {
        //STEP 3: loading the EMF model
        resourceA.load( options );
        //STEP 4: accessing the EMF model (depends on your model)
        this.documentRoot = ( DocumentRoot )resourceA.getContents().get( 0  
);
        this.jobDefinition = this.documentRoot.getJobDefinition();
        this.jobDescription = this.jobDefinition.getJobDescription();
        this.jobIdentification = this.documentRoot.getJobIdentification();
      } catch( IOException ioEx ) {
        if( ioEx instanceof IOWrappedException ) {
          IOWrappedException ioWEx = ( IOWrappedException )ioEx;
          throw ioWEx;
        }
      }
    }
  }

Is this solution with java.io.file OK or do you need the one for not  
serialized String?

Cheers,
Kasia
