Interface ConnectionProxy

All Superinterfaces:
  Connection, Wrapper

    public interface ConnectionProxy

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.
