[jira] [Resolved] (ETCH-109) C Binding: Mixins not fully functional

["Michael Fitzner (JIRA)" <ji...@apache.org>]

Michael Fitzner resolved ETCH-109.
----------------------------------

    Resolution: Fixed

The Mixin feature was added to the binding-c implementation. This change will also introduce an incompatibility to your current binding-c stub implementations. The function mapping inside the implementation modules have to be changed to the new structure.

Setting the implementation method in *_impl.c files have to be changed e.g. from

pserver->say_hello = pserver_base->say_hello = say_hello_impl;

to

etchmap_insertxw(pserver_base->virtuals, helloworld_valufact_get_static()->str_helloworld_say_hello, say_hello_impl, FALSE);

An example can be found at examples/example_mixin
