Note: AnnotationMirrors are immutable.

  • Method Details

    • annotationName

      public static final @CanonicalName String annotationName(AnnotationMirror annotation)
      Returns the fully-qualified name of an annotation as a String.
      Parameters:
      annotation - the annotation whose name to return
      Returns:
      the fully-qualified name of an annotation as a String
    • annotationBinaryName

      public static final @BinaryName String annotationBinaryName(AnnotationMirror annotation)
      Returns the binary name of an annotation as a String.
      Parameters:
      annotation - the annotation whose binary name to return
      Returns:
      the binary name of an annotation as a String
    • areSame

      @EqualsMethod public static boolean areSame(AnnotationMirror a1, AnnotationMirror a2)
      Returns true iff both annotations are of the same type and have the same annotation values.

      This behavior differs from AnnotationMirror.equals(Object). The equals method returns true iff both annotations are the same and annotate the same annotation target (e.g. field, variable, etc) -- that is, if its arguments are the same annotation instance.

      Parameters:
      a1 - the first AnnotationMirror to compare
      a2 - the second AnnotationMirror to compare
      Returns:
      true iff a1 and a2 are the same annotation
    • compareByName

      @EqualsMethod public static int compareByName(AnnotationMirror a1, AnnotationMirror a2)
      Return -1, 0, or 1 depending on whether the name of a1 is less, equal to, or greater than that of a2 (lexicographically).
      Parameters:
      a1 - the first AnnotationMirror to compare
      a2 - the second AnnotationMirror to compare
      Returns:
      true iff a1 and a2 have the same annotation name
      See Also:
    • areSameByName

      @EqualsMethod public static boolean areSameByName(AnnotationMirror a1, AnnotationMirror a2)
      Return true iff a1 and a2 have the same annotation type.
      Parameters:
      a1 - the first AnnotationMirror to compare
      a2 - the second AnnotationMirror to compare
      Returns:
      true iff a1 and a2 have the same annotation name
      See Also:
    • areSameByName

      public static boolean areSameByName(AnnotationMirror am, String aname)
      Checks that the annotation am has the name aname (a fully-qualified type name). Values are ignored.
      Parameters:
      am - the AnnotationMirror whose name to compare
      aname - the string to compare
      Returns:
      true if aname is the name of am
    • areSameByClass

      @Deprecated public static boolean areSameByClass(AnnotationMirror am, Class<? extends Annotation> annoClass)
      Checks that the annotation am has the name of annoClass. Values are ignored.

      This method is not very efficient. It is more efficient to use AnnotatedTypeFactory#areSameByClass or areSameByName(javax.lang.model.element.AnnotationMirror, javax.lang.model.element.AnnotationMirror).

      Parameters:
      am - the AnnotationMirror whose class to compare
      annoClass - the class to compare
      Returns:
      true if annoclass is the class of am
    • areSame

      public static boolean areSame(Collection<? extends AnnotationMirror> c1, Collection<? extends AnnotationMirror> c2)
      Checks that two collections contain the same annotations.
      Parameters:
      c1 - the first collection to compare
      c2 - the second collection to compare
      Returns:
      true iff c1 and c2 contain the same annotations, according to areSame(AnnotationMirror, AnnotationMirror)
    • containsSame

      public static boolean containsSame(Collection<? extends AnnotationMirror> c, AnnotationMirror anno)
      Checks that the collection contains the annotation. Using Collection.contains does not always work, because it does not use areSame for comparison.
      Parameters:
      c - a collection of AnnotationMirrors
      anno - the AnnotationMirror to search for in c
      Returns:
      true iff c contains anno, according to areSame
    • getSame

      public static @Nullable AnnotationMirror getSame(Collection<? extends AnnotationMirror> c, AnnotationMirror anno)
      Returns the AnnotationMirror in c that is the same annotation as anno.
      Parameters:
      c - a collection of AnnotationMirrors
      anno - the AnnotationMirror to search for in c
      Returns:
      AnnotationMirror with the same class as anno iff c contains anno, according to areSame; otherwise, null
    • containsSameByClass

      public static boolean containsSameByClass(Collection<? extends AnnotationMirror> c, Class<? extends Annotation> anno)
      Checks that the collection contains the annotation. Using Collection.contains does not always work, because it does not use areSame for comparison.

      This method is not very efficient. It is more efficient to use AnnotatedTypeFactory#containsSameByClass or containsSameByName(java.util.Collection<? extends javax.lang.model.element.AnnotationMirror>, java.lang.String).

      Parameters:
      c - a collection of AnnotationMirrors
      anno - the annotation class to search for in c

      public static @Nullable AnnotationMirror getAnnotationByClass(Collection<? extends AnnotationMirror> c, Class<? extends Annotation> anno)
      Returns the AnnotationMirror in c that has the same class as anno.

      This method is not very efficient. It is more efficient to use AnnotatedTypeFactory#getAnnotationByClass or getAnnotationByName(java.util.Collection<? extends javax.lang.model.element.AnnotationMirror>, java.lang.String).

      Parameters:
      c - a collection of AnnotationMirrors
      anno - the class to search for in c
      Returns:
      AnnotationMirror with the same class as anno iff c contains anno, according to areSameByClass; otherwise, null
    • containsSameByName

      public static boolean containsSameByName(Collection<? extends AnnotationMirror> c, String anno)
      Checks that the collection contains an annotation of the given name. Differs from using Collection.contains, which does not use areSameByName for comparison.
      Parameters:

      Returns:
      the set of ElementKinds corresponding to elementType
    • getElementValue

      @Deprecated public static <T> T getElementValue(AnnotationMirror anno, CharSequence elementName, Class<T> expectedType, boolean useDefaults)
      Get the element with the name elementName of the annotation anno. The result has type expectedType.

      If the return type is an array, use getElementValueArray(javax.lang.model.element.AnnotationMirror, java.lang.CharSequence, java.lang.Class<T>, boolean) instead.

      If the return type is an enum, use getElementValueEnum(javax.lang.model.element.AnnotationMirror, javax.lang.model.element.ExecutableElement, java.lang.Class<T>) instead.

      This method is intended only for use by the framework. A checker implementation should use getElementValue(AnnotationMirror, ExecutableElement, Class) or getElementValue(AnnotationMirror, ExecutableElement, Class, Object).

      Type Parameters:
      T - the class of the type
      Parameters:
      anno - the annotation whose element to access
      elementName - the name of the element to access

      useDefaults - whether to apply default values to the element
      Returns:
      the value of the element with the given name
    • getElementValueOrNull

      public static <T> @Nullable T getElementValueOrNull(AnnotationMirror anno, CharSequence elementName, Class<T> expectedType, boolean useDefaults)
      Get the element with the name elementName of the annotation anno, or return null if no such element exists.

      This method is intended only for use by the framework. A checker implementation should use getElementValue(AnnotationMirror, ExecutableElement, Class, Object).

      Type Parameters:
      T - the class of the type
      Parameters:
      anno - the annotation whose element to access
      elementName - the name of the element to access
      expectedType - the type of the element and the return value
      useDefaults - whether to apply default values to the element
      Returns:
      the value of the element with the given name, or null
    • getElementValueArrayOrNull

      public static <T> @Nullable List<T> getElementValueArrayOrNull(AnnotationMirror anno, CharSequence elementName, Class<T> expectedType, boolean useDefaults)
      Get the element with the name elementName of the annotation anno, or return null if no such element exists. One element of the result has type expectedType.

      This method is intended only for use by the framework. A checker implementation should use getElementValue(AnnotationMirror, ExecutableElement, Class, Object).

      Type Parameters:
      T - the class of the component type
      Parameters:
      anno - the annotation whose element to access
      elementName - the name of the element to access
      expectedType - the component type of the element and of the return value
      useDefaults - whether to apply default values to the element
      Returns:
      the value of the element with the given name, or null
    • getElementValueArray

      @Deprecated public static <T> List<T> getElementValueArray(AnnotationMirror anno, CharSequence elementName, Class<T> expectedType, boolean useDefaults)
      Deprecated.
      use #getElementValueArray(AnnotationMirror, ExecutableElement, Class) or #getElementValueArray(AnnotationMirror, ExecutableElement, Class, Object)
      Get the element with the name elementName of the annotation anno, where the element has an array type. One element of the result has type expectedType.

      Parameter useDefaults is used to determine whether default values should be used for annotation values. Finding defaults requires more computation, so should be false when no defaulting is needed.

      This method is intended only for use by the framework. A checker implementation should use #getElementValueArray(AnnotationMirror, ExecutableElement, Class) or #getElementValueArray(AnnotationMirror, ExecutableElement, Class, Object).

      Type Parameters:
      T - the class of the type
      Parameters:
      anno - the annotation to disassemble
      elementName - the name of the element to access
      expectedType - the component type of the element and of the return type
      useDefaults - whether to apply default values to the element
      Returns:
      the value of the element with the given name; it is a new list, so it is safe for clients to side-effect
    • getElementValueClassName

      Deprecated.
      use an ExecutableElement
      Get the Name of the class that is referenced by element elementName.

      This is a convenience method for the most common use-case. It is like getElementValue(anno, elementName, ClassType.class).getQualifiedName(), but this method ensures consistent use of the qualified name.

      This method is intended only for use by the framework. A checker implementation should use anno.getElementValues().get(someElement).getValue().asElement().getQualifiedName();.

      Parameters:
      anno - the annotation to disassemble
      elementName - the name of the element to access; it must be present in the annotation
      useDefaults - whether to apply default values to the element
      Returns:

      Using this method is slightly cheaper than creating a new List just for the purpose of testing containment within it.

      Parameters:
      avList - a list of Strings (as AnnotationValues)
      s - a string
      Returns:
      true if av contains s
    • annotationValueToList

      public static <T> List<T> annotationValueToList(AnnotationValue avList, Class<T> expectedType)
      Converts an annotation value to a list.

      To test containment, use annotationValueContains(AnnotationValue, String) or annotationValueContainsToString(AnnotationValue, String).

      Type Parameters:
      T - the class of the type
      Parameters:
      avList - an AnnotationValue that is a list of Strings
      expectedType - the component type of the argument and of the return type, an enum
      Returns:
      the annotation value, converted to a list
    • annotationValueToList

      public static <T> List<T> annotationValueToList(List<? extends AnnotationValue> avList, Class<T> expectedType)
      Converts an annotation value to a list.

      To test containment, use annotationValueContains(List, String) or annotationValueContainsToString(List, String).

      Type Parameters:
      T - the class of the type
      Parameters:
      avList - a list of Strings (as AnnotationValues)
      expectedType - the component type of the argument and of the return type, an enum
      Returns:
      the annotation value, converted to a list
    • updateMappingToImmutableSet

      public static <T extends @NonNull Object> void updateMappingToImmutableSet(Map<T,AnnotationMirrorSet> map, T key, AnnotationMirrorSet newQual)
      Update a map, to add newQual to the set that key maps to. The mapped-to element is an unmodifiable set.

      See org.checkerframework.framework.type.QualifierHierarchy#updateMappingToMutableSet(QualifierHierarchy, Map, Object, AnnotationMirror).

      Type Parameters:
      T - the key type
      Parameters:
      map - the map to update
      key - the key whose value to update
      newQual - the element to add to the given key's value
    • getExplicitAnnotationsOnConstructorResult

      public static AnnotationMirrorSet getExplicitAnnotationsOnConstructorResult(MethodTree constructorDeclaration)
      Returns the annotations explicitly written on a constructor result. Callers should check that constructorDeclaration is in fact a declaration of a constructor.
      Parameters:
      constructorDeclaration - declaration tree of constructor
      Returns:
      set of annotations explicit on the resulting type of the constructor
    • isDeclarationAnnotation

      public static boolean isDeclarationAnnotation(AnnotationMirror anno)
      Returns true if anno is a declaration annotation. In other words, returns true if anno cannot be written on uses of types.
      Parameters:
      anno - the AnnotationMirror
      Returns:
      true if anno is a declaration annotation
    • hasTypeQualifierElementTypes

      public static boolean hasTypeQualifierElementTypes(ElementType[] elements, Class<?> cls)
      Returns true if the given array contains ElementType.TYPE_USE, false otherwise.
      Parameters:
      elements - an array of ElementType values
      cls - the annotation class being tested; used for diagnostic messages only
      Returns:
      true iff the give array contains ElementType.TYPE_USE
      Throws:
      RuntimeException - if the array contains both ElementType.TYPE_USE and something besides ElementType.TYPE_PARAMETER
    • toStringSimple

      @SideEffectFree public static String toStringSimple(AnnotationMirrorSet annos)
      Returns a string representation of the annotation mirrors, using simple (not fully-qualified) names.
      Parameters:
      annos - annotations to format
      Returns:
      the string representation, using simple (not fully-qualified) names
    • annotationMirrorToClass

      public static Class<?> annotationMirrorToClass(AnnotationMirror am)
      Converts an AnnotationMirror to a Class. Throws an exception if it is not able to do so.
      Parameters:
      am - an AnnotationMirror
      Returns:
      the Class corresponding to the given AnnotationMirror
