Class C3P0NativeJdbcExtractor

java.lang.Object
  org.springframework.jdbc.support.nativejdbc.NativeJdbcExtractorAdapter
      com.atlassian.confluence.ext.jdbc.support.nativejdbc.C3P0NativeJdbcExtractor

All Implemented Interfaces:

org.springframework.jdbc.support.nativejdbc.NativeJdbcExtractor

public class C3P0NativeJdbcExtractor
extends org.springframework.jdbc.support.nativejdbc.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 OracleResultSet.

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

Constructor Summary

C3P0NativeJdbcExtractor()

Method Summary

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.
