Examples of narrowBy()

com.fasterxml.jackson.databind.JavaType.narrowBy()
Method that can be called to do a "narrowing" conversions; that is, to return a type with a raw class that is assignable to the raw class of this type. If this is not possible, an {@link IllegalArgumentException} is thrown.If class is same as the current raw class, instance itself is returned.

Examples of com.fasterxml.jackson.databind.JavaType.narrowBy()

        /* both narrow and widen just return type itself (exact, not just
         * equal)
         * (also note that widen/narrow wouldn't work on basic simple
         * class type otherwise)
         */
        assertSame(baseType, baseType.narrowBy(BaseType.class));
        assertSame(baseType, baseType.widenBy(BaseType.class));


        // Also: no narrowing for simple types (but should there be?)
        try {
            baseType.narrowBy(SubType.class);
