Example 26 with Filer

use of javax.annotation.processing.Filer in project tycho by eclipse.

the class JSR269Processor method process.

@Override
public boolean process(Set<? extends TypeElement> annotations, RoundEnvironment roundEnv) {
    if (!roundEnv.processingOver()) {
        final Filer filer = processingEnv.getFiler();
        try {
            final JavaFileObject sourceFile = filer.createSourceFile("tycho590.processed.Processor");
            Writer sourceWriter = sourceFile.openWriter();
            sourceWriter.append("package tycho590.processed;");
            sourceWriter.append(String.format("%n"));
            sourceWriter.append("public class Processor {}");
            sourceWriter.close();
        } catch (IOException ex) {
            // That will happen on round 2 because source file already exists
            System.out.println("[APT] " + ex.getMessage());
        }
    }
    return false;

Example 27 with Filer

use of javax.annotation.processing.Filer in project potato by eyeem.

the class Processor method process.

@Override
public boolean process(Set<? extends TypeElement> annotations, RoundEnvironment roundEnv) {
    ArrayList<CodeWriter> writers = new ArrayList<>();
    Filer filer = processingEnv.getFiler();

    for (TypeElement annotation : annotations) {
        // region for every class annotated with the annotation
        for (Element element : roundEnv.getElementsAnnotatedWith(annotation)) {
