public ClassValAnnotatedTypeFactory(BaseTypeChecker checker)
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
