Method Detail

• isMarker

  public static boolean isMarker(Class<? extends Annotation> annotationType)

  Returns true if the given annotation type has no attributes.

• isAllDefaultMethods

  public static boolean isAllDefaultMethods(Class<? extends Annotation> annotationType)

• generateAnnotation

  public static <T extends Annotation> T generateAnnotation(Class<T> annotationType)

  Generates an Annotation for the annotation class. Requires that the annotation is all optionals.

• isRetainedAtRuntime

  public static boolean isRetainedAtRuntime(Class<? extends Annotation> annotationType)

  Returns true if the given annotation is retained at runtime.

• findScopeAnnotation

  public static Class<? extends Annotation> findScopeAnnotation(Errors errors,
                                                                Class<?> implementation)

  Returns the scope annotation on type, or null if none is specified.

• findScopeAnnotation

  public static Class<? extends Annotation> findScopeAnnotation(Errors errors,
                                                                Annotation[] annotations)

  Returns the scoping annotation, or null if there isn't one.

• memberValueString

  public static String memberValueString(String value)

  Returns value, quoted if annotation implementations quote their member values. In Java 9, annotations quote their string members.

• isScopeAnnotation

  public static boolean isScopeAnnotation(Class<? extends Annotation> annotationType)

• checkForMisplacedScopeAnnotations

  public static void checkForMisplacedScopeAnnotations(Class<?> type,
                                                       Object source,
                                                       Errors errors)

  Adds an error if there is a misplaced annotations on type. Scoping annotations are not allowed on abstract classes or interfaces.

• getKey

  public static Key<?> getKey(TypeLiteral<?> type,
                              Member member,
                              Annotation[] annotations,
                              Errors errors)
                       throws ErrorsException

  Gets a key for the given type, member and annotations.

  Throws:

  ErrorsException

• findBindingAnnotation

  public static Annotation findBindingAnnotation(Errors errors,
                                                 Member member,
                                                 Annotation[] annotations)

  Returns the binding annotation on member, or null if there isn't one.

• isBindingAnnotation

  public static boolean isBindingAnnotation(Class<? extends Annotation> annotationType)

  Returns true if annotations of the specified type are binding annotations.

• canonicalizeIfNamed

  public static Annotation canonicalizeIfNamed(Annotation annotation)

  If the annotation is an instance of javax.inject.Named, canonicalizes to com.google.guice.name.Named. Returns the given annotation otherwise.

• canonicalizeIfNamed

  public static Class<? extends Annotation> canonicalizeIfNamed(Class<? extends Annotation> annotationType)

  If the annotation is the class javax.inject.Named, canonicalizes to com.google.guice.name.Named. Returns the given annotation class otherwise.

• nameOf

  public static String nameOf(Key<?> key)

  Returns the name the binding should use. This is based on the annotation. If the annotation has an instance and is not a marker annotation, we ask the annotation for its toString. If it was a marker annotation or just an annotation type, we use the annotation's name. Otherwise, the name is the empty string.
