It's required for dynamic ingestion of models from network devices and plugins. The primary use case for dynamic model ingestion is Netconf/Restconf. For plugins written in java, code can be generated at compile time in tools, but this will not generally be the case for models coming from network devices, other platforms and from plugins that will be written in different languages. </p> <p>The decision to use/not use run time code generation should be left to the integrator that puts together a particular controller distribution.</p> <p>Actually migrating from runtime-generated code to compile time will introduce another dependency - generated binding will start to be dependent on Binding-independent data representation (which is now separated). </p> <p>This will complicate deploying changes in serialization (performance improvements, bugfixes) since affected jars needs to be recreate, and decrease flexibility of system. </p> <p>So I would rather look into how to make this part easier to understand, rather then removing it in general.</p> <p><a href="https://git.opendaylight.org/gerrit/#/c/18820/" class="external-link" target="_blank" rel="nofollow noopener">https://git.opendaylight.org/gerrit/#/c/18820/</a></p> <p>Reopening it as it is not related to the patch which was commented (or I am missing the relationship).</p> <p>Runtime code-generation was removed from md-sal and yangtools codecs,<br/> only generated code is StreamEmmiter, which only decomposes binding data<br/> to set of events. Actual codec and processing part is hand-written.</p> Development External issue ID 1094 External issue URL ODL SR Target Milestone Priority Rank 0|i02kw7:
