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>
Heron needs to know how to serialize all the values in a tuple. By default, Heron
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>
