Final Keyword
-------------
Key: THRIFT-178
URL: https://issues.apache.org/jira/browse/THRIFT-178
Project: Thrift
Issue Type: New Feature
Components: Compiler (C++), Compiler (General), Compiler (Java)
Reporter: Erik Frey
Priority: Minor
This introduces support for the final keyword in the thrift IDL. A C++ thrift
struct that is declared final loses it's virtual dtor, which saves the memory
overhead of one vtable per instance. This (along with the required keyword)
can be very helpful if you're passing around big lists of small thrift structs.
This patch also includes modifications for the java generator to recognize and
apply final. I'm not familiar enough with the other languages to know if this
notion applies to them.
(A patch for this was submitted in thrift's pre-apache days and was met with
approval, but then fell off the radar, so I'm trying again.)
