Method Summary

Modifier and Type	Method and Description
static String	extractRequestedProviderName(PersistenceUnitDescriptor persistenceUnit, Map integration) Extract the requested persistence provider name using the algorithm Hibernate uses.
static boolean	hibernateProviderNamesContain(String requestedProviderName) Is the requested provider name one of the recognized Hibernate provider names?
static boolean	isProvider(PersistenceUnitDescriptor persistenceUnit, Map integration) Does the descriptor and/or integration request Hibernate as the PersistenceProvider? Note that in the case of no requested provider being named we assume we are the provider (the calls got to us somehow...)

Method Detail

isProvider

public static boolean isProvider(PersistenceUnitDescriptor persistenceUnit,
                                 Map integration)

Does the descriptor and/or integration request Hibernate as the PersistenceProvider? Note that in the case of no requested provider being named we assume we are the provider (the calls got to us somehow...)

Parameters:

persistenceUnit - The <persistence-unit/> descriptor.

integration - The integration values.

Returns:

true if Hibernate should be the provider; false otherwise.

hibernateProviderNamesContain

public static boolean hibernateProviderNamesContain(String requestedProviderName)

Is the requested provider name one of the recognized Hibernate provider names?

Parameters:

requestedProviderName - The requested provider name to check against the recognized Hibernate names.

Returns:

true if Hibernate should be the provider; false otherwise.

extractRequestedProviderName

public static String extractRequestedProviderName(PersistenceUnitDescriptor persistenceUnit,
                                                  Map integration)

Extract the requested persistence provider name using the algorithm Hibernate uses. Namely, a provider named in the 'integration' map (under the key '') is preferred, as per-spec, over value specified in persistence unit.

Parameters:

persistenceUnit - The <persistence-unit/> descriptor.

integration - The integration values.

Returns:

The extracted provider name, or null if none found.
