| Generate specific Java classes for schemas and protocols. |
| |
| <p>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. |
| |
| <p>Avro types are mapped to Java as follows: |
| |
| <ul> |
| |
| <li>Record, enum, and fixed schemas generate Java class definitions.</li> |
| |
| <li>If a Conversion instance is available for the related logical type, |
| the value will be mapped to the object returned by that Conversion. The |
| logical type conversions for {@code date}, {@code time-millis}, {@code |
| timestamp-millis} and {@code decimal} are pre-defined in the class {@link |
| <a href="../../../../org/apache/avro/compiler/specific/SpecificCompiler.html" title="class in org.apache.avro.compiler.specific"><code>SpecificCompiler</code></a>}.</li> |
| |
| <li>All other types are mapped as in the {@link org.apache.avro.generic |
| generic} API.</li> |
| |
| </ul> |
| |
| <p>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. |
