public class StringTrimmedResultSet extends Object implements InvocationHandler
ResultSet to trim strings returned by the
getString() and getObject() methods.
Usage Example:
This example shows how to decorate ResultSets so processing continues as
normal but all Strings are trimmed before being returned from the
ResultSet.
ResultSet rs = // somehow get a ResultSet; // Substitute wrapped ResultSet with additional behavior for real ResultSet rs = StringTrimmedResultSet.wrap(rs); // Pass wrapped ResultSet to processor List list = new BasicRowProcessor().toBeanList(rs);
