Method Details

createAnnotationClassLoader

protected AnnotationClassLoader createAnnotationClassLoader()

Description copied from class: AnnotatedTypeFactory

Factory method to easily change what AnnotationClassLoader is created to load type annotation classes. Subclasses can override this method and return a custom AnnotationClassLoader subclass to customize loading logic.

Overrides:

createAnnotationClassLoader in class AnnotatedTypeFactory

createSupportedTypeQualifiers

protected Set<Class<? extends Annotation>> createSupportedTypeQualifiers()

Description copied from class: AnnotatedTypeFactory

Returns a mutable set of annotation classes that are supported by a checker.

Subclasses may override this method to return a mutable set of their supported type qualifiers through one of the 5 approaches shown below.

Subclasses should not call this method; they should call AnnotatedTypeFactory.getSupportedTypeQualifiers() instead.

By default, a checker supports all annotations located in a subdirectory called qual that's located in the same directory as the checker. Note that only annotations defined with the @Target({ElementType.TYPE_USE}) meta-annotation (and optionally with the additional value of ElementType.TYPE_PARAMETER, but no other ElementType values) are automatically considered as supported annotations.

To support a different set of annotations than those in the qual subdirectory, or that have other ElementType values, see examples below.

In total, there are 5 ways to indicate annotations that are supported by a checker:

1. Only support annotations located in a checker's qual directory:

   This is the default behavior. Simply place those annotations within the qual directory.

2. Support annotations located in a checker's qual directory and a list of other annotations:

   Place those annotations within the qual directory, and override AnnotatedTypeFactory.createSupportedTypeQualifiers() by calling AnnotatedTypeFactory.getBundledTypeQualifiers(Class...) with a varargs parameter list of the other annotations. Code example:

    @Override protected Set<Class<? extends Annotation>> createSupportedTypeQualifiers() {
         return getBundledTypeQualifiers(Regex.class, PartialRegex.class, RegexBottom.class, UnknownRegex.class);
     } 
    

3. Supporting only annotations that are explicitly listed: Override AnnotatedTypeFactory.createSupportedTypeQualifiers() and return a mutable set of the supported annotations. Code example:

    @Override protected Set<Class<? extends Annotation>> createSupportedTypeQualifiers() {
         return new HashSet<Class<? extends Annotation>>(
                 Arrays.asList(A.class, B.class));
     } 
    

   The set of qualifiers returned by AnnotatedTypeFactory.createSupportedTypeQualifiers() must be a fresh, mutable set. The methods AnnotatedTypeFactory.getBundledTypeQualifiers(Class...) must return a fresh, mutable set

Overrides:

createSupportedTypeQualifiers in class AnnotatedTypeFactory

Returns:

the type qualifiers supported this processor, or an empty set if none

addCheckedCodeDefaults

protected void addCheckedCodeDefaults(QualifierDefaults defs)

If necessary, make Unqualified the default qualifier. Keep most logic in sync with super.

Overrides:

addCheckedCodeDefaults in class GenericAnnotatedTypeFactory<CFValue,CFStore,CFTransfer,CFAnalysis>

Parameters:

defs - the QualifierDefault object to which defaults are added
