java.lang.Objectorg.apache.commons.dbutils.wrappers.StringTrimmedResultSet
Wraps a 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 = BasicRowProcessor.instance().toBeanList(rs);
