Subject [jira] [Commented] (AVRO-1961) [JAVA] Generate getters that return an Optional
Date Fri, 02 Dec 2016 01:23:58 GMT

    [ https://issues.apache.org/jira/browse/AVRO-1961?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15713643#comment-15713643

Yibing Shi commented on AVRO-1961:

Actually, on the setter/builder/constructor, we could even go a step further: a required field
with a default value could be with Optional<Foo> as well. The matching getter would
be without Optional. It would make the concept of default value type safe just as well. Sweet
isn't it?
And Optional object indicates that the value could be null. It has a different meaning than
having a default value. That is, you can skip passing in a value for this field doesn't mean
you can pass in a null value for this field. Suggest not to apply this to fields with default

1. Java 8 isn't required for Avro project for this to work
All the "magic" happen uniquely through the template: the code could still compile with Java
6, but anyone using the "pojoWithOptional" flag should consume the generated pojo with Java
8 or backport Optional.
Is Java 8 is needed to test the pojoWithOptionalGenerationTest you are going to add?

would be very useful for him.
