Examples with GeneratorDelegate org.eclipse.xtext.generator.GeneratorDelegate used on opensource projects

Example 1 with GeneratorDelegate

use of org.eclipse.xtext.generator.GeneratorDelegate in project n4js by eclipse.

the class XStatefulIncrementalBuilder method generate.

/**
 * Generate code for the given resource
 */
protected void generate(Resource resource, XSource2GeneratedMapping newMappings, IResourceServiceProvider serviceProvider) {
    GeneratorDelegate generator = serviceProvider.get(GeneratorDelegate.class);
    if (generator == null) {
        return;
    }
    if (isResourceInOutputDirectory(resource, serviceProvider)) {
        return;
    }
    URI source = resource.getURI();
    Set<URI> previous = newMappings.deleteSource(source);
    URIBasedFileSystemAccess fileSystemAccess = this.createFileSystemAccess(serviceProvider, resource);
    fileSystemAccess.setBeforeWrite((uri, outputCfgName, contents) -> {
        newMappings.addSource2Generated(source, uri, outputCfgName);
        previous.remove(uri);
        request.afterGenerate(source, uri);
        return contents;
    });
    fileSystemAccess.setBeforeDelete((uri) -> {
        newMappings.deleteGenerated(uri);
        request.afterDelete(uri);
        return true;
    });
    fileSystemAccess.setContext(resource);
    if (request.isWriteStorageResources() && resource instanceof StorageAwareResource) {
        IResourceStorageFacade resourceStorageFacade = ((StorageAwareResource) resource).getResourceStorageFacade();
        if (resourceStorageFacade != null) {
            resourceStorageFacade.saveResource((StorageAwareResource) resource, fileSystemAccess);
        }
    }
    if (request.canGenerate()) {
        GeneratorContext generatorContext = new GeneratorContext();
        generatorContext.setCancelIndicator(request.getCancelIndicator());
        generator.generate(resource, fileSystemAccess, generatorContext);
        XtextResourceSet resourceSet = request.getResourceSet();
        for (URI noLongerCreated : previous) {
            try {
                resourceSet.getURIConverter().delete(noLongerCreated, CollectionLiterals.emptyMap());
                request.afterDelete(noLongerCreated);
            } catch (IOException e) {

Example 2 with GeneratorDelegate

use of org.eclipse.xtext.generator.GeneratorDelegate in project ArchCNL by Mari-Wie.

the class CNL2OWLGenerator method transformCNLFile.

/**
 * Translates the given file from ArchCNL's CNL to OWL. The resulting OWL ontology is written to
 * the specified output file.
 *
 * @param path The path of the file to transform.
 * @param outputPath The path of the output file.
 * @return The RuleType of the parsed rule or null when something went wrong.
 * @throws IOException
 */
