public class LockAnnotatedTypeFactory extends GenericAnnotatedTypeFactory<CFValue,LockStore,LockTransfer,LockAnalysis>
However, there are a number of other annotations used in conjunction with these annotations to enforce proper locking.

protected Set<Class<? extends Annotation>> createSupportedTypeQualifiers()
AnnotatedTypeFactory
Subclasses may override this method and 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 PolyAll
, and 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.
Annotations located outside the qual subdirectory, or has other ElementType
values must be explicitly listed in code by overriding the AnnotatedTypeFactory.createSupportedTypeQualifiers()
method, as shown below.
Lastly, for checkers that do not want to support PolyAll
, it must also be
explicitly written in code, as shown below.
In total, there are 5 ways to indicate annotations that are supported by a checker:
PolyAll
:
This is the default behavior. Simply place those annotations within the qual directory.
PolyAll
:
Place those annotations within the qual directory, and override AnnotatedTypeFactory.createSupportedTypeQualifiers()
by calling AnnotatedTypeFactory.getBundledTypeQualifiersWithPolyAll(Class...)
with no parameters passed in. Code
example:
@Override protected Set<Class<? extends Annotation>> createSupportedTypeQualifiers() {
return getBundledTypeQualifiersWithoutPolyAll();
}
PolyAll
,
and a list of other annotations:
Place those annotations within the qual directory, and override AnnotatedTypeFactory.createSupportedTypeQualifiers()
by calling AnnotatedTypeFactory.getBundledTypeQualifiersWithPolyAll(Class...)
with a varargs parameter list of the
other annotations. Code example:
@Override protected Set<Class<? extends Annotation>> createSupportedTypeQualifiers() {
return getBundledTypeQualifiersWithPolyAll(Regex.class, PartialRegex.class, RegexBottom.class, UnknownRegex.class);
}
PolyAll
:
Place those annotations within the qual directory, and override AnnotatedTypeFactory.createSupportedTypeQualifiers()
by calling AnnotatedTypeFactory.getBundledTypeQualifiersWithoutPolyAll(Class...)
with a varargs parameter list of the
other annotations. Code example:
@Override protected Set<Class<? extends Annotation>> createSupportedTypeQualifiers() {
return getBundledTypeQualifiersWithoutPolyAll(UnknownFormat.class, FormatBottom.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.getBundledTypeQualifiersWithoutPolyAll(Class...)
and AnnotatedTypeFactory.getBundledTypeQualifiersWithPolyAll(Class...)
each must return a fresh, mutable set

This implementation uses the checker naming convention to create the appropriate analysis.
If no transfer function is found, it returns an instance of CFAnalysis
.
Subclasses have to override this method to create the appropriate analysis if they do not follow the checker naming convention.

TreeAnnotator
that adds annotations to a type based on the contents of a

Subclasses may override this method to specify a more appropriate TreeAnnotator
.
The default tree annotator is a ListTreeAnnotator
of the following:
PropagationTreeAnnotator
: Propagates annotations from subtrees.
ImplicitsTreeAnnotator
: Adds annotations based on ImplicitFor
