Examples with ClassModel javaslang.match.model.ClassModel used on opensource projects

Example 1 with ClassModel

use of javaslang.match.model.ClassModel in project javaslang by javaslang.

the class PatternsProcessor method generate.

// Expands all @Patterns classes
private void generate(Set<ClassModel> classModels) {
    final Filer filer = processingEnv.getFiler();
    for (ClassModel classModel : classModels) {
        final String derivedClassName = deriveClassName(classModel);
        final String code = Generator.generate(derivedClassName, classModel);
        final String fqn = (classModel.hasDefaultPackage() ? "" : classModel.getPackageName() + ".") + derivedClassName;
        try (final Writer writer = filer.createSourceFile(fqn, classModel.typeElement()).openWriter()) {
            writer.write(code);
        } catch (IOException x) {
            throw new Error("Error writing " + fqn, x);
        }
    }
}

Example 2 with ClassModel

use of javaslang.match.model.ClassModel in project javaslang by javaslang.

the class PatternsProcessor method transform.

// Verify correct usage of annotations @Patterns and @Unapply
private Set<ClassModel> transform(Set<TypeElement> typeElements) {
    final Set<ClassModel> classModels = new HashSet<>();
    final javax.lang.model.util.Elements elementUtils = processingEnv.getElementUtils();
    final Messager messager = processingEnv.getMessager();
    for (TypeElement typeElement : typeElements) {
        final ClassModel classModel = ClassModel.of(elementUtils, typeElement);
        final List<MethodModel> methodModels = classModel.getMethods().stream().filter(method -> method.isAnnotatedWith(Unapply.class)).collect(toList());
        if (methodModels.isEmpty()) {
            messager.printMessage(Diagnostic.Kind.WARNING, "No @Unapply methods found.", classModel.typeElement());
        } else {
            final boolean methodsValid = methodModels.stream().reduce(true, (bool, method) -> bool && UnapplyChecker.isValid(method.getExecutableElement(), messager), (b1, b2) -> b1 && b2);
            if (methodsValid) {
                classModels.add(classModel);
            }
        }
    }
    return classModels;
