Examples with Target java.lang.annotation.Target used on opensource projects

Example 21 with Target

use of java.lang.annotation.Target in project auto by google.

the class FactoryWriter method isTypeUseAnnotation.

private static boolean isTypeUseAnnotation(AnnotationMirror mirror) {
    Element annotationElement = mirror.getAnnotationType().asElement();
    // This is basically equivalent to:
    // Target target = annotationElement.getAnnotation(Target.class);
    // return target != null
    // && Arrays.asList(annotationElement.getAnnotation(Target.class)).contains(TYPE_USE);
    // but that might blow up if the annotation is being compiled at the same time and has an
    // undefined identifier in its @Target values. The rigmarole below avoids that problem.
    Optional<AnnotationMirror> maybeTargetMirror = Mirrors.getAnnotationMirror(annotationElement, Target.class);
    return maybeTargetMirror.map(targetMirror -> AnnotationValues.getEnums(AnnotationMirrors.getAnnotationValue(targetMirror, "value")).stream().map(VariableElement::getSimpleName).anyMatch(name -> name.contentEquals("TYPE_USE"))).orElse(false);
}

Example 22 with Target

use of java.lang.annotation.Target in project querydsl by querydsl.

the class ScalaWriterTest method Annotation_With_ArrayMethod.

@Test
public void Annotation_With_ArrayMethod() throws IOException {
    Target annotation = new Target() {

        @Override
        public ElementType[] value() {
            return new ElementType[] { ElementType.FIELD, ElementType.METHOD };
        }

        @Override
        public Class<? extends Annotation> annotationType() {
            return Target.class;
        }
    };
    writer.imports(Target.class.getPackage());
    writer.annotation(annotation);
    assertTrue(w.toString().contains("@Target(Array(FIELD, METHOD))"));
}

Example 23 with Target

use of java.lang.annotation.Target in project querydsl by querydsl.

the class JavaWriterTest method Annotation_With_ArrayMethod.

@Test
public void Annotation_With_ArrayMethod() throws IOException {
    Target annotation = new Target() {

        @Override
        public ElementType[] value() {
            return new ElementType[] { ElementType.FIELD, ElementType.METHOD };
        }

        @Override
        public Class<? extends Annotation> annotationType() {
            return Target.class;
        }
    };
    writer.imports(Target.class.getPackage());
    writer.annotation(annotation);
    assertTrue(w.toString().contains("@Target({FIELD, METHOD})"));
}

Example 24 with Target

use of java.lang.annotation.Target in project wire by square.

the class JavaGenerator method generateOptionType.

// Example:
// 
// @Retention(RetentionPolicy.RUNTIME)
// @Target(ElementType.FIELD)
// public @interface MyFieldOption {
// String value();
// }
@Nullable
public TypeSpec generateOptionType(Extend extend, Field field) {
    checkArgument(extend.getFields().contains(field));
    if (!emitDeclaredOptions)
        return null;
    ElementType elementType = annotationTargetType(extend);
    if (elementType == null)
        return null;
    if (!eligibleAsAnnotationMember(schema, field))
        return null;
    TypeName returnType = typeName(field.getType());
    ClassName javaType = generatedTypeName(field);
    TypeSpec.Builder builder = TypeSpec.annotationBuilder(javaType.simpleName()).addModifiers(PUBLIC).addAnnotation(AnnotationSpec.builder(Retention.class).addMember("value", "$T.$L", RetentionPolicy.class, RetentionPolicy.RUNTIME).build()).addAnnotation(AnnotationSpec.builder(Target.class).addMember("value", "$T.$L", ElementType.class, elementType).build());
    if (!field.getDocumentation().isEmpty()) {
        builder.addJavadoc("$L\n", field.getDocumentation());
    }
    builder.addMethod(MethodSpec.methodBuilder("value").returns(returnType).addModifiers(PUBLIC, ABSTRACT).build());
    return builder.build();
