Subject [jira] [Commented] (AVRO-1961) [JAVA] Generate getters that return an Optional
Date Wed, 23 Nov 2016 10:54:58 GMT

ASF GitHub Bot commented on AVRO-1961:

GitHub user nielsbasjes opened a pull request:


    AVRO-1961: Java: Generate getters that return a Java 8 Optional.

    NOTE: This must wait until AFTER the release of Avro 1.8.2.
    This is a first attempt at making the Java code generator have the option (default is
off) to generate Java 8 Optional getters.
    A few things about this that open and must be discussed before committing:
    1. This will change the building of Avro to require JDK 8 to be installed. Building with
JDK 7 will simply fail.
    2. The main runtime is still compiled with the setting "JDK 6". So in theory that should
remain backward compatible for systems that still rely in JDK 6.
    3. This is my first time playing with Optionals so a thorough review is really needed.
    Also a big question is: Do we want this? 
    I think it is a good idea to use the new Java features that make it easier for downstream
    Yet the risk of breaking backward compatibility may be considered to be a problem.
