[jira] Commented: (THRIFT-238) Generated structs should have constructor option to skip default values

Kevin Clark commented on THRIFT-238:
------------------------------------

I'm not sure I like the idea, but if we wanted to do it, we could probably just add a second, optional, arg to the generated initialize.

> It seems like it would be useful to have an overload (or option) on struct constructors to skip the initialization of default values. The particular use case I'm thinking about is when you are going to be using an instance of a struct to read from a protocol, and you don't want the "merging" effect that could happen if you have optional fields with default values. It could be very simple - for instance, in Java, it could just be a constructor like MyStruct(boolean useDefaults), and the existing no-arg constructor would call that with true.
