org.springframework.jdbc.support.nativejdbc.C3P0NativeJdbcExtractor
public class C3P0NativeJdbcExtractor
Implementation of the NativeJdbcExtractor
interface for the
C3P0 connection pool.
Returns underlying native Connections to application code instead of C3P0's
wrapper implementations; unwraps the Connection for native Statements.
The returned JDBC classes can then safely be cast, e.g. to
oracle.jdbc.OracleConnection
.
This NativeJdbcExtractor can be set just to allow working with a C3P0 DataSource: If a given object is not a C3P0 wrapper, it will be returned as-is.
Note that this class requires C3P0 0.8.5 or later; for earlier C3P0 versions, use SimpleNativeJdbcExtractor (which won't work for C3P0 0.8.5 or later).

protected Connection |
doGetNativeConnection(Connection con)
Retrieve the Connection via C3P0's rawConnectionOperation API,
using the getRawConnection as callback to get access to the
raw Connection (which is otherwise not directly supported by C3P0). |
static Connection |
getRawConnection(Connection con)
This method is not meant to be used directly; it rather serves as callback method for C3P0's "rawConnectionOperation" API. |

isNativeConnectionNecessaryForNativeCallableStatements()
Return false by default. |
boolean |
isNativeConnectionNecessaryForNativePreparedStatements()
Return false by default. |
boolean |
isNativeConnectionNecessaryForNativeStatements()
Return false by default. |
