Generate specific Java classes for schemas and protocols.

This API is recommended for most RPC uses and for data applications that always use the same datatypes, i.e., whose schemas are known at compile time. For data applications that accept dynamic datatypes the {@link org.apache.avro.generic generic} API is recommended.

Avro types are mapped to Java as follows:

- Record, enum, and fixed schemas generate Java class definitions.
- All other types are mapped as in the {@link org.apache.avro.generic generic} API.

Note that when a generated class is not found corresponding to a record, enum or fixed schema, a {@link org.apache.avro.generic generic} representation is used. This permits generated classes to be nested within generic data structures.
