Class Overview

Extension of the javax.sql.DataSource interface, to be implemented by special DataSources that return JDBC Connections in an unwrapped fashion.

Classes using this interface can query whether or not the Connection should be closed after an operation. Spring's DataSourceUtils and JdbcTemplate classes automatically perform such a check.
