Example 1 with IFileSystemAccess

use of org.eclipse.xtext.generator.IFileSystemAccess in project joynr by bmwcarit.

the class AbstractGeneratorTest method invokeGenerator.

protected void invokeGenerator(IGenerator generator, String fileName, String outputDirectory, String... referencedResources) {
    final IFileSystemAccess fileSystemAccess = createFileSystemAccess(outputDirectory);
    final URI uri = URI.createFileURI(new File(fileName).getAbsolutePath());
    final Set<URI> uris = new HashSet<URI>();
    uris.add(uri);
    for (String refRes : referencedResources) {
        uris.add(URI.createFileURI(new File(refRes).getAbsolutePath()));
    }
    File file = new File(fileName);
    IUriProvider uriProvider = null;
    if (file.isDirectory()) {
        uriProvider = new FolderUriProvider(Sets.newHashSet("fidl"), file);
    } else {
        uriProvider = new IUriProvider() {

            @Override
            public Iterable<URI> allUris() {
                return Lists.newArrayList(uris);
            }
        };
    }
    ModelStore modelStore = ModelStore.modelsIn(uriProvider);
    for (URI foundUri : uriProvider.allUris()) {
        final Resource r = modelStore.getResource(foundUri);
        generator.doGenerate(r, fileSystemAccess);
    }
}

Example 2 with IFileSystemAccess

use of org.eclipse.xtext.generator.IFileSystemAccess in project xtext-eclipse by eclipse.

the class JavaProjectBasedBuilderParticipant method build.
