def _wrapWithSerialization(self, aCallable, command): (source)

Wrap aCallable with its command's argument de-serialization and result serialization logic.

Parameters
aCallable	a callable with a 'command' attribute, designed to be called with keyword arguments.
command	the command class whose serialization to use.
Returns
a 1-arg callable which, when invoked with an AmpBox, will deserialize the argument list and invoke appropriate user code for the callable's command, returning a Deferred which fires with the result or fails with an error.
