Method Detail

getDeclAndTypeUseAnnotationTypes

private static java.util.Set<JavaTypeInstance> getDeclAndTypeUseAnnotationTypes(java.util.List<AnnotationTableEntry> declAnnotations,
                                                                                java.util.List<AnnotationTableTypeEntry> typeAnnotations)

getCommonInnerClassAnnotationIndex

private static java.lang.Integer getCommonInnerClassAnnotationIndex(java.util.List<AnnotationTableTypeEntry> typeAnnotations)

Returns for the annotations the common inner class annotation index, or null if there is no common index. For example with A and B being inner classes:

{@code

Parameters:

typeAnnotations - For which the common inner annotation index should be determined

Returns:

Common annotation index or null

canTypeAnnotationBeMovedToDecl

private static boolean canTypeAnnotationBeMovedToDecl(JavaTypeInstance annotatedType,
                                                      AnnotationTableTypeEntry typeAnnotation,
                                                      java.lang.Integer commonInnerAnnotationIndex)

Returns whether the type annotation can be moved to the declaration. For example:

{@code
 // Can be moved
 public @TypeUse String[] f;
 // when moved:

Parameters:

annotatedType - Type to be annotated

typeAnnotation - Annotation for the type

commonInnerAnnotationIndex - Nullable index of the common annotation position for inner classes

Returns:

Whether the annotation can be moved to the declaration

areAnnotationsEqual

private static boolean areAnnotationsEqual(java.util.List<AnnotationTableEntry> declAnnotations,
                                           java.util.List<AnnotationTableTypeEntry> typeAnnotations)

getDeclarationInfo

public static DeclarationAnnotationHelper.DeclarationAnnotationsInfo getDeclarationInfo(JavaTypeInstance nullableAnnotatedType,
                                                                                        java.util.List<AnnotationTableEntry> declarationAnnotations,
                                                                                        java.util.List<AnnotationTableTypeEntry> typeAnnotations)

Calculates information about where to place declaration and ElementType.TYPE_USE annotations for a place where both can occur.

Parameters:

nullableAnnotatedType - Type for which the TYPE_USE annotations apply, null if there is no type (e.g. for constructor declarations)

declarationAnnotations - Annotations for the declaration, e.g. ElementType.FIELD

typeAnnotations - Annotations for the type, i.e. ElementType.TYPE_USE

Returns:

Information about how to place the annotations
