Interface ResultSetHandler<T>

Type Parameters:

T - the type of result returned by the handler

public interface ResultSetHandler<T>

A closure that handles the result set returned by a query.

This interface provides the means for an JdbcQuery query to process the results of a query in an arbitrary fashion.

While the handleResult(ResultSet) method can return a value, it is not always necessary. When an implementation does not need to return a value, simply use Void as the type parameter.

Example:

 ResultSetHandler<Void> handler = new ResultSetHandler<>() {
   public Void handleResult(ResultSet rs) throws SQLException {
     while (rs.next()) {
       exporter.exportPerson(rs.getLong("id"), rs.getString("name"));
     }
     return null;
   }
 };
