// <synopsis>
// SSMDirColumn handles the access to a column containing direct
// arrays of the various data types.
// <br>
// It is derived from <linkto class=SSMColumn>SSMColumn</linkto>
// and uses most of its functions. The only thing done differently
// in this class is that it maintains no cache.
// Furthermore fixed length strings are not handled specially.
// All string arrays are stored in the special string buckets.
