- - org.springframework.jdbc.support.nativejdbc.C3P0NativeJdbcExtractor

All Implemented Interfaces:
NativeJdbcExtractor
```
public class C3P0NativeJdbcExtractor
extends NativeJdbcExtractorAdapter
```
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).
Since:
1.1.5

Method Summary

All Methods Static Methods Instance Methods Concrete Methods
Modifier and Type	Method	Description
`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.
`boolean`	`isNativeConnectionNecessaryForNativeCallableStatements()`	Return `false` by default.
`boolean`	`isNativeConnectionNecessaryForNativePreparedStatements()`	Return `false` by default.
`boolean`	`isNativeConnectionNecessaryForNativeStatements()`	Return `false` by default.
