java.lang.Object checkers.util.QualifierPolymorphism
public class QualifierPolymorphism
Implements framework support for type qualifier polymorphism. Checkers that
wish to use it should add calls to
#annotate(MethodInvocationTree, AnnotatedExecutableType)
and
annotate(Element, AnnotatedTypeMirror)
to the
AnnotatedTypeFactory.annotateImplicit(Tree, AnnotatedTypeMirror)
and
AnnotatedTypeFactory.annotateImplicit(Tree, AnnotatedTypeMirror)
methods.
This implementation currently only supports polymorphism for method invocations, for which the return type depends on the unification of the parameter/receiver types.
