Method Detail

getConnectionProvider

public ConnectionProvider getConnectionProvider()

setConnectionProvider

public void setConnectionProvider(ConnectionProvider connectionProvider)

injectServices

public void injectServices(ServiceRegistryImplementor serviceRegistry)

Description copied from interface: ServiceRegistryAwareService

Callback to inject the registry.

Specified by:

injectServices in interface ServiceRegistryAwareService

Parameters:

serviceRegistry - The registry

configure

public void configure(Map<String,Object> configurationValues)

Description copied from interface: Configurable

Configure the service.

Specified by:

configure in interface Configurable

Parameters:

configurationValues - The configuration properties.

getConnection

public Connection getConnection()
                         throws SQLException

Description copied from interface: ConnectionProvider

Obtains a connection for Hibernate use according to the underlying strategy of this provider.

Specified by:

getConnection in interface ConnectionProvider

Returns:

The obtained JDBC connection

Throws:

SQLException - Indicates a problem opening a connection

closeConnection

public void closeConnection(Connection connection)
                     throws SQLException

Description copied from interface: ConnectionProvider

Release a connection from Hibernate use.

Specified by:

closeConnection in interface ConnectionProvider

Parameters:

connection - The JDBC connection to release

Throws:

SQLException - Indicates a problem closing the connection

supportsAggressiveRelease

public boolean supportsAggressiveRelease()

Description copied from interface: ConnectionProvider

Does this connection provider support aggressive release of JDBC connections and later re-acquisition of those connections if needed?

This is used in conjunction with ConnectionReleaseMode.AFTER_STATEMENT to aggressively release JDBC connections. However, the configured ConnectionProvider must support re-acquisition of the same underlying connection for that semantic to work.

Typically, this is only true in managed environments where a container tracks connections by transaction or thread.

Note that JTA semantic depends on the fact that the underlying connection provider does support aggressive release.

Specified by:

supportsAggressiveRelease in interface ConnectionProvider

Returns:

true if aggressive releasing is supported; false otherwise.

getDatabaseConnectionInfo

public DatabaseConnectionInfo getDatabaseConnectionInfo(Dialect dialect)

Specified by:

getDatabaseConnectionInfo in interface ConnectionProvider

isUnwrappableAs

public boolean isUnwrappableAs(Class<?> unwrapType)

Description copied from interface: Wrapped

Can this wrapped service be unwrapped as the indicated type?

Specified by:

isUnwrappableAs in interface Wrapped

Parameters:

unwrapType - The type to check.

Returns:

True/false.

unwrap

public <T> T unwrap(Class<T> unwrapType)

Description copied from interface: Wrapped

Unproxy the service proxy

Specified by:

unwrap in interface Wrapped

Parameters:

unwrapType - The java type as which to unwrap this instance.

Returns:

The unwrapped reference

stop

public void stop()

Description copied from interface: Stoppable

Stop phase notification

Specified by:

stop in interface Stoppable
