Examples of org.apache.avro.Protocol

org.apache.avro.Protocol
A set of messages forming an application protocol.
A protocol consists of:
- a name for the protocol;
- an optional namespace, further qualifying the name;
- a list of types, or named {@link Schema schemas};
- a list of errors, or named {@link Schema schemas} for exceptions;
- a list of named messages, each of which specifies,
  - request, the parameter schemas;
  - one of either;
    - one-way
    or
    - response, the response schema;
    - errors, an optional list of potential error schema names.
