public class Chain
extends Object

Chain reads two NTuple tables as one NTuple. It gets a token_string String from each row which satisfies a simple filter. RowRepresentants are created from those Strings and accumulated in an array. Database and NTuple (table) should exist.
Chain is an example to show chaining API and capabilities of SQLTuple.
