Methods in this class may be overridden subject to their aoqi@0: * general contract. Note that annotating methods in concrete aoqi@0: * subclasses with {@link java.lang.Override @Override} will help aoqi@0: * ensure that methods are overridden as intended. aoqi@0: * aoqi@0: *
WARNING: The {@code TypeVisitor} interface implemented aoqi@0: * by this class may have methods added to it in the future to aoqi@0: * accommodate new, currently unknown, language structures added to aoqi@0: * future versions of the Java™ programming language. aoqi@0: * Therefore, methods whose names begin with {@code "visit"} may be aoqi@0: * added to this class in the future; to avoid incompatibilities, aoqi@0: * classes which extend this class should not declare any instance aoqi@0: * methods with names beginning with {@code "visit"}. aoqi@0: * aoqi@0: *
When such a new visit method is added, the default aoqi@0: * implementation in this class will be to call the {@link aoqi@0: * #visitUnknown visitUnknown} method. A new simple type visitor aoqi@0: * class will also be introduced to correspond to the new language aoqi@0: * level; this visitor will have different default behavior for the aoqi@0: * visit method in question. When the new visitor is introduced, all aoqi@0: * or portions of this visitor may be deprecated. aoqi@0: * aoqi@0: *
Note that adding a default implementation of a new visit method
aoqi@0: * in a visitor class will occur instead of adding a default
aoqi@0: * method directly in the visitor interface since a Java SE 8
aoqi@0: * language feature cannot be used to this version of the API since
aoqi@0: * this version is required to be runnable on Java SE 7
aoqi@0: * implementations. Future versions of the API that are only required
aoqi@0: * to run on Java SE 8 and later may take advantage of default methods
aoqi@0: * in this situation.
aoqi@0: *
aoqi@0: * @param the type of the additional parameter to this visitor's
aoqi@0: * methods. Use {@code Void} for visitors that do not need an
aoqi@0: * additional parameter.
