Interface ConnectionProxy

All Superinterfaces:: Connection, Wrapper

public interface ConnectionProxy
extends Connection
extends Connection

Subinterface of Connection to be implemented by Connection proxies. Allows access to the underlying target Connection.

This interface can be checked when there is a need to cast to a native JDBC Connection such as Oracle's OracleConnection. Spring's NativeJdbcExtractorAdapter automatically detects such proxies before delegating to the actual unwrapping for a specific connection pool.
