                            throws java.sql.SQLException

Description copied from interface: ConnectionPlugin

Establishes a connection to the given host using the given driver protocol and properties. If a non-default ConnectionProvider has been set with Driver.setCustomConnectionProvider(ConnectionProvider) and ConnectionProvider.acceptsUrl(String, HostSpec, Properties) returns true for the given protocol, host, and properties, the connection will be created by the non-default ConnectionProvider. Otherwise, the connection will be created by the default ConnectionProvider. The default ConnectionProvider will be DriverConnectionProvider for connections requested via the DriverManager and DataSourceConnectionProvider for connections requested via an AwsWrapperDataSource.

Specified by:

connect in interface ConnectionPlugin

Overrides:

connect in class AbstractConnectionPlugin

Parameters:

driverProtocol - the driver protocol that should be used to establish the connection

hostSpec - the host details for the desired connection

props - the connection properties

isInitialConnection - a boolean indicating whether the current Connection is establishing an initial physical connection to the database or has already established a physical connection in the past

connectFunc - the function to call to continue the connect request down the connect pipeline

Returns:

a Connection to the requested host

Throws:

java.sql.SQLException - if there was an error establishing a Connection to the requested host

regularOpenConnection

protected java.sql.Connection regularOpenConnection(JdbcCallable<java.sql.Connection,java.sql.SQLException> connectFunc,
                                                    boolean isInitialConnection)
                                             throws java.sql.SQLException

Throws:

java.sql.SQLException
