| <div class="block">The tuple is the main data structure in Storm. A tuple is a named list of values, where each value can be any type. Tuples are |
| dynamically typed -- the types of the fields do not need to be declared. Tuples have helper methods like getInteger and getString to get |
| field values without having to cast the result. |
| |
| <p>Storm needs to know how to serialize all the values in a tuple. By default, Storm knows how to serialize the primitive types, strings, |
| and byte arrays. If you want to use another type, you'll need to implement and register a serializer for that type.</div> |
