public static JdbcSupport

Returns:

An appropriate JdbcSupport instance.
loadJdbcSupport(Connection
A JDBC java.sql.Connection which can be used to gauge the drivers level of support, specifically for creating LOB references.
jdbcConnection)

The public factory method for obtaining the appropriate (according to given JDBC java.sql.Connection) JdbcSupport.

private static boolean

Returns:

True if the connection can be used to create LOBs; false otherwise.
useContextualLobCreation(Connection
The connection which can be used in level-of-support testing.

Method Detail

loadJdbcSupportback to summary
public static JdbcSupport loadJdbcSupport(Connection jdbcConnection)

The public factory method for obtaining the appropriate (according to given JDBC java.sql.Connection) JdbcSupport.

Parameters
jdbcConnection:Connection

A JDBC java.sql.Connection which can be used to gauge the drivers level of support, specifically for creating LOB references.

Returns:JdbcSupport

An appropriate JdbcSupport instance.

useContextualLobCreationback to summary
private static boolean useContextualLobCreation(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.
