Method Detail

getServiceInitiated

public Class<ConnectionProvider> getServiceInitiated()

Description copied from interface: ServiceInitiator

Obtains the service role initiated by this initiator. Should be unique within a registry

Specified by:

getServiceInitiated in interface ServiceInitiator<ConnectionProvider>

Returns:

The service role.

initiateService

                                          ServiceRegistryImplementor registry)

Description copied from interface: StandardServiceInitiator

Initiates the managed service.

Specified by:

initiateService in interface StandardServiceInitiator<ConnectionProvider>

Parameters:

configurationValues - The configuration values in effect

registry - The service registry. Can be used to locate services needed to fulfill initiation.

Returns:

The initiated service.

getConnectionProperties

public static Properties getConnectionProperties(Map<?,?> properties)

Build the connection properties capable of being passed to the DriverManager.getConnection(java.lang.String, java.util.Properties) forms taking Properties argument. We seek out all keys in the passed map which start with hibernate.connection., using them to create a new Properties instance. The keys in this new Properties have the hibernate.connection. prefix trimmed.

Parameters:

properties - The map from which to build the connection specific properties.

Returns:

The connection properties.

extractIsolation

public static Integer extractIsolation(Map settings)

interpretIsolation

public static Integer interpretIsolation(Object setting)

toIsolationConnectionConstantName

public static String toIsolationConnectionConstantName(Integer isolation)

Gets the Connection constant name corresponding to the given isolation.

Parameters:

isolation - The transaction isolation numeric value.

Returns:

The corresponding Connection constant name.

Throws:

HibernateException - If the given isolation does not map to JDBC standard isolation

See Also:

toIsolationNiceName(java.lang.Integer)

toIsolationNiceName

public static String toIsolationNiceName(Integer isolation)

Get the name of a JDBC transaction isolation level

Parameters:

isolation - The transaction isolation numeric value.

Returns:

a nice human-readable name
