Class JdbcTemplate.RowCallbackHandlerResultSetExtractor

java.lang.Object
  org.springframework.jdbc.core.JdbcTemplate.RowCallbackHandlerResultSetExtractor

All Implemented Interfaces:

ResultSetExtractor<java.lang.Object>

Enclosing class:

JdbcTemplate

private static class JdbcTemplate.RowCallbackHandlerResultSetExtractor
extends java.lang.Object
implements ResultSetExtractor<java.lang.Object>

Adapter to enable use of a RowCallbackHandler inside a ResultSetExtractor.

Uses a regular ResultSet, so we have to be careful when using it: We don't use it for navigating since this could lead to unpredictable consequences.

Description copied from interface: ResultSetExtractor

Implementations must implement this method to process the entire ResultSet.

Specified by:

extractData in interface ResultSetExtractor<java.lang.Object>

Parameters:

rs - ResultSet to extract data from. Implementations should not close this: it will be closed by the calling JdbcTemplate.

Returns:

an arbitrary result object, or null if none (the extractor will typically be stateful in the latter case).

Throws:

java.sql.SQLException - if a SQLException is encountered getting column values or navigating (that is, there's no need to catch SQLException)
