private static String extractProviderName(PersistenceUnitDescriptor persistenceUnit)
extractRequestedProviderNameback to summary
public static String extractRequestedProviderName(PersistenceUnitDescriptor persistenceUnit, Map<K, V> integration)

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

Parameters
persistenceUnit:PersistenceUnitDescriptor

The <persistence-unit/> descriptor.

integration:Map<K, V>

The integration values.

Returns:String

The extracted provider name, or null if none found.

hibernateProviderNamesContainback to summary
public static boolean hibernateProviderNamesContain(String requestedProviderName)

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

Parameters
requestedProviderName:String

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

Returns:boolean

true if Hibernate should be the provider; false otherwise.

isProviderback to summary
public static boolean isProvider(PersistenceUnitDescriptor persistenceUnit, Map<K, V> integration)

Does the descriptor and/or integration request Hibernate as the javax.persistence.spi.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:PersistenceUnitDescriptor

The <persistence-unit/> descriptor.

integration:Map<K, V>

The integration values.

Returns:boolean

true if Hibernate should be the provider; false otherwise.
