Interface JdbcConnection

All Superinterfaces:

java.lang.AutoCloseable, java.sql.Connection, MysqlConnection, TransactionEventHandler, java.sql.Wrapper

All Known Subinterfaces:

LoadBalancedConnection, ReplicationConnection

All Known Implementing Classes:

ConnectionImpl, ConnectionWrapper, LoadBalancedMySQLConnection, MultiHostMySQLConnection, ReplicationMySQLConnection

public interface JdbcConnection
extends java.sql.Connection, MysqlConnection, TransactionEventHandler

This interface contains methods that are considered the "vendor extension" to the JDBC API for MySQL's implementation of java.sql.Connection. For those looking further into the driver implementation, it is not an API that is used for plugability of implementations inside our driver (which is why there are still references to ConnectionImpl throughout the code).
