Class AbstractTypeVisitor6<R,​P>

  • Type Parameters:
    R - the return type of this visitor's methods. Use Void for visitors that do not need to return results.
    P - the type of the additional parameter to this visitor's methods. Use Void for visitors that do not need an additional parameter.
    All Implemented Interfaces:
    javax.lang.model.type.TypeVisitor<R,​P>
    Direct Known Subclasses:
    AbstractTypeVisitor7, SimpleTypeVisitor6

    @SupportedSourceVersion(RELEASE_6)
    public abstract class AbstractTypeVisitor6<R,​P>
    extends java.lang.Object
    implements javax.lang.model.type.TypeVisitor<R,​P>
    A skeletal visitor of types with default behavior appropriate for the RELEASE_6 source version.

    WARNING: The TypeVisitor interface implemented by this class may have methods added to it in the future to accommodate new, currently unknown, language structures added to future versions of the Java™ programming language. Therefore, methods whose names begin with "visit" may be added to this class in the future; to avoid incompatibilities, classes which extend this class should not declare any instance methods with names beginning with "visit".

    When such a new visit method is added, the default implementation in this class will be to call the visitUnknown method. A new abstract type visitor class will also be introduced to correspond to the new language level; this visitor will have different default behavior for the visit method in question. When the new visitor is introduced, all or portions of this visitor may be deprecated.

    Since:
    1.6

      • visit

        public final R visit​(javax.lang.model.type.TypeMirror t,
                             P p)
        Visits any type mirror as if by passing itself to that type mirror's accept method. The invocation v.visit(t, p) is equivalent to t.accept(v, p).
        Specified by:
        visit in interface javax.lang.model.type.TypeVisitor<R,​P>
        Parameters:
        t - the type to visit
        p - a visitor-specified parameter
        Returns:
        a visitor-specified result
      • visit

        public final R visit​(javax.lang.model.type.TypeMirror t)
        Visits any type mirror as if by passing itself to that type mirror's accept method and passing null for the additional parameter. The invocation v.visit(t) is equivalent to t.accept(v, null).
        Specified by:
        visit in interface javax.lang.model.type.TypeVisitor<R,​P>
        Parameters:
        t - the type to visit
        Returns:
        a visitor-specified result
      • visitUnion

        public R visitUnion​(javax.lang.model.type.UnionType t,
                            P p)
        Visits a union type.
        Specified by:
        visitUnion in interface javax.lang.model.type.TypeVisitor<R,​P>
        Parameters:
        t - the type to visit
        p - a visitor-specified parameter
        Returns:
        the result of visitUnknown
        Since:
        1.7
      • visitIntersection

        public R visitIntersection​(javax.lang.model.type.IntersectionType t,
                                   P p)
        Visits an intersection type.
        Specified by:
        visitIntersection in interface javax.lang.model.type.TypeVisitor<R,​P>
        Parameters:
        t - the type to visit
        p - a visitor-specified parameter
        Returns:
        the result of visitUnknown
        Since:
        1.8
      • visitUnknown

        public R visitUnknown​(javax.lang.model.type.TypeMirror t,
                              P p)
        Visits an unknown kind of type. This can occur if the language evolves and new kinds of types are added to the TypeMirror hierarchy.
        Specified by:
        visitUnknown in interface javax.lang.model.type.TypeVisitor<R,​P>
        Parameters:
        t - the type to visit
        p - a visitor-specified parameter
        Returns:
        a visitor-specified result
        Throws:
        javax.lang.model.type.UnknownTypeException - a visitor implementation may optionally throw this exception
