java.lang.Object org.springframework.jdbc.support.nativejdbc.NativeJdbcExtractorAdapter org.springframework.jdbc.support.nativejdbc.XAPoolNativeJdbcExtractor
public class XAPoolNativeJdbcExtractor
Implementation of the NativeJdbcExtractor interface for ObjectWeb's XAPool.
Returns underlying native Connections and native PreparedStatements to
application code instead of XAPool's wrapper implementations; unwraps the
Connection for native Statements and native CallableStatements.
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 an XAPool DataSource: If a given object is not an XAPool wrapper, it will be returned as-is.
