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

----------------------------------

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?
{quote}
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
values.

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.
{quote}
Is Java 8 is needed to test the pojoWithOptionalGenerationTest you are going to add?

would be very useful for him.
