public LobCreator

Returns:

The LobCreator
buildLobCreator(LobCreationContext
The LOB creation context
lobCreationContext)

Build a LobCreator using the given context

private static boolean

Returns:

True if the connection can be used to create LOBs; false otherwise.
useContextualLobCreation(Map<K, V> configValues, Connection
The connection which can be used in level-of-support testing.
jdbcConnection)

Basically here we are simply checking whether we can call the Connection methods for LOB creation added in JDBC 4.

public LobCreator buildLobCreator(LobCreationContext lobCreationContext)

Build a LobCreator using the given context

Parameters
lobCreationContext:LobCreationContext

The LOB creation context

Returns:LobCreator

The LobCreator

useContextualLobCreationback to summary
private static boolean useContextualLobCreation(Map<K, V> 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
jdbcConnection:Connection

The connection which can be used in level-of-support testing.

Returns:boolean

True if the connection can be used to create LOBs; false otherwise.
