Hi Klement,
There have "autoreply define classify_add_del_session" in classify.api .
And /usr/include/vnet/classify/classify.api.h have the
"vl_api_classify_add_del_session".
And the java jar have the "classify_add_del_session" class too!
But the classify.api.vapi.h don't have ！！！

Simon

Hi,
VAPI is autogenerated from .json files, which are generated from .api
files. The API you are asking about is in
src/vnet/classify/classify.api. See that file's history on when it
appeared. As for your second question - I don't see any `obscure-mask`
nor `clear-param` parameters. If you are asking about semantics of the
API call, that is a question for the author of said API, since VAPI is
generated code.
Regards,
Klement
