public static EnumSet<LobTypes> getSupportedContextualLobTypes(Dialect dialect, Map<String, Object> configValues, Connection jdbcConnection) Basically here we are simply checking whether we can call the `Connection` methods for LOB creation added in JDBC 4. We not only check whether the `Connection` declares these methods, but also whether the actual `Connection` instance implements them (i.e. can be called without simply throwing an exception). Parameters dialect:Dialect The `Dialect` in use configValues:Map<String, Object> The map of settings jdbcConnection:Connection The connection which can be used in level-of-support testing.
