      Is this a complex column.
      private boolean isLongVary
      Is this a variable length column using longs? [Must have isVarying true too]
      private boolean isString
      Is this a string column.
      private boolean isVarying
      Is this a variable length column ?
      private java.lang.Object model
      An example of the kind of data that should be read/written in one row
