Ordered Map in Thrift

[Dheeraj Goswami <dh...@yahoo.com>]

Hi,I have the requirement to use Map but keep it ordered (Like LinkedHashMap in java). Is there a way to define thrift IDL to generate the ordered map in Java and C++ languages?

thanks,

This doesn't exist as a Thrift feature. You'll need to separately maintain a list to preserve ordering using Thrift off-the-shelf.

Another route to take would be to use some of the annotations to tell Thrift what data-types to use for the map type. If you provide container types that implement ordering, they can be swapped out. I don't recall off the top of my head what the syntax is on these type annotations or how deep the support is -- perhaps someone else can chime in there, or you might look through the implementation.
