protected Set<Class<? extends Annotation>> createSupportedTypeQualifiers()
AnnotatedTypeFactory
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:
This is the default behavior. Simply place those annotations within the qual directory.
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);
}
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

The default implementation returns the type without considering dataflow type refinement. Subclass can override this method and add additional logic for computing the type of a LHS.

protected TreeAnnotator createTreeAnnotator()
GenericAnnotatedTypeFactory
TreeAnnotator
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 subtrees
LiteralTreeAnnotator
: Adds annotations based on QualifierForLiterals
meta-annotations
DependentTypesTreeAnnotator
: 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));
