Examples of com.fasterxml.jackson.databind.ObjectWriter.withType()

com.fasterxml.jackson.databind.ObjectWriter.withType()
Method that will construct a new instance that uses specific type as the root type for serialization, instead of runtime dynamic type of the root object itself.
Note that method does NOT change state of this reader, but rather construct and returns a newly configured instance.

         }


         // Most of the configuration now handled through EndpointConfig, ObjectWriter
         // but we may need to force root type:
         if (rootType != null) {
            writer = writer.withType(rootType);
         }
         value = endpoint.modifyBeforeWrite(value);
         writer.writeValue(jg, value);
      } finally {
         jg.close();

                     * if we set it for regular types, jackson will build the serializer based on this type, and not the
                     * instance type, making polymorphic returns broken.
                     * For parameterized types it helps Jackson which otherwise tries to guess the serializer based on
                     * value.getClass() which doesn't return type parameters information due to Java erasure.
