lookup()

PersistableFactory const & lsst::afw::table::io::PersistableFactory::lookup ( std::string const &  name, std::string const &  module = ""  )

staticinherited

Return the factory that has been registered with the given name.

If the lookup fails and module is not an empty string, we will attempt to import a Python module with that name (this will only work when the C++ is being called from Python) and try again.
