void PLearn::SDBVMFieldNormalize::convertField (  const SDBWithStats &  sdb, const Row &  row, const Vec &  output )  const [virtual]

Given a database row, convert the appropriate parts to a (preallocated) output vector of the correct width (given by fieldWidth). Replace MISSING_VALUEs by missing_values_mapping.
