createSupportedTypeQualifiers
protected java.util.Set<java.lang.Class<? extends java.lang.annotation.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 ofElementType.TYPE_PARAMETER
, but no otherElementType
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:
- Only support annotations located in a checker's qual directory:
This is the default behavior. Simply place those annotations within the qual directory.
- 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 callingAnnotatedTypeFactory.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); }
- 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)); }
AnnotatedTypeFactory.createSupportedTypeQualifiers()
must be a fresh, mutable set. The methodsAnnotatedTypeFactory.getBundledTypeQualifiers(Class...)
must return a fresh, mutable set
- Overrides:
createSupportedTypeQualifiers
in classAnnotatedTypeFactory
- Returns:
- the type qualifiers supported this processor, or an empty set if none
- Only support annotations located in a checker's qual directory:
-
getClassNamesFromAnnotation
public java.util.List<java.lang.String> getClassNamesFromAnnotation(javax.lang.model.element.AnnotationMirror anno)
Returns the list of classnames from@ClassBound
or@ClassVal
if anno is@ClassBound
or@ClassVal
, otherwise returns an empty list.- Parameters:
anno
- any AnnotationMirror- Returns:
- list of classnames in anno
-
createQualifierHierarchy
protected QualifierHierarchy createQualifierHierarchy()
Description copied from class:AnnotatedTypeFactory
Returns theQualifierHierarchy
to be used by this checker.The implementation builds the type qualifier hierarchy for the
AnnotatedTypeFactory.getSupportedTypeQualifiers()
using the meta-annotations found in them. The current implementation returns an instance ofNoElementQualifierHierarchy
.Subclasses must override this method if their qualifiers have elements; the method must return an implementation of
QualifierHierarchy
, such asElementQualifierHierarchy
.- Overrides:
createQualifierHierarchy
in classAnnotatedTypeFactory
- Returns:
- a QualifierHierarchy for this type system
-
createTreeAnnotator
protected TreeAnnotator createTreeAnnotator()
Description copied from class:GenericAnnotatedTypeFactory
Returns aTreeAnnotator
that adds annotations to a type based on the contents of a tree.The default tree annotator is a
ListTreeAnnotator
of the following:PropagationTreeAnnotator
: Propagates annotations from subtreesLiteralTreeAnnotator
: Adds annotations based onQualifierForLiterals
meta-annotationsDependentTypesTreeAnnotator
: Adapts dependent annotations based on context
Subclasses may override this method to specify additional tree annotators, for example:
new ListTreeAnnotator(super.createTreeAnnotator(), new KeyLookupTreeAnnotator(this));
- Overrides:
createTreeAnnotator
in classGenericAnnotatedTypeFactory<CFValue,CFStore,CFTransfer,CFAnalysis>
- Returns:
- a tree annotator
