Class QualifierPolymorphism

java.lang.Object
  checkers.util.QualifierPolymorphism

public class QualifierPolymorphism
extends Object

Implements framework support for type qualifier polymorphism. Checkers that wish to use it should add calls to annotate(Tree, AnnotatedTypeMirror) 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.
