      • isUpperBound

        public boolean isUpperBound()
        Return true if this is an upper type bound, e.g. <? extends Integer>, or the unbounded wildcard <?>.

      • isLowerBound

        public boolean isLowerBound()
        Returns true if this is a lower type bound, e.g. in <? super Node>.

      • getTypeBoundNode

        public @Nullable ASTReferenceType getTypeBoundNode()
        Returns the type node representing the bound, e.g. the Node in <? super Node>, or null in the unbounded wildcard <?>.

      • acceptVisitor

        protected <P,​R> R acceptVisitor​(JavaVisitor<? super P,​? extends R> visitor,
                                      P data)

      • getTypeMirror

        public @NonNull JTypeMirror getTypeMirror()
        Description copied from interface: TypeNode
        Returns the compile-time type of this node. For example, for a string literal, returns the type mirror for String, for a method call, returns the return type of the call, etc.

        This method ignores conversions applied to the value of the node because of its context. For example, in 1 + "", the numeric literal will have type int, but it is converted to String by the surrounding concatenation expression. Similarly, in Collections.singletonList(1), the ASTNumericLiteral node has type int, but the type of the method formal is Integer, and boxing is applied at runtime. Possibly, an API will be added to expose this information.

        Specified by:
        getTypeMirror in interface TypeNode
        Returns:
        The type mirror. Never returns null; if the type is unresolved, returns TypeSystem.UNKNOWN.
