Method Detail

resolveEntityManagerQualifiers

public Set<Class<? extends Annotation>> resolveEntityManagerQualifiers(org.apache.deltaspike.jpa.api.transaction.Transactional transactionalAnnotation,
                                                              Class interceptedTargetClass)

This method uses the InvocationContext to scan the @Transactional interceptor for a manually specified Qualifier.

If none is given (defaults to Any.class) then we scan the intercepted instance and resolve the Qualifiers of all it's injected EntityManagers.

Please note that we will only pickup the first Qualifier on the injected EntityManager. We also do not parse for binding or &h#064;NonBinding values. A @Qualifier should not have any parameter at all.

Parameters:

transactionalAnnotation - the @Transactional annotation found on the intercepted class

interceptedTargetClass - the Class of the intercepted target

extractTransactionalAnnotation

protected org.apache.deltaspike.jpa.api.transaction.Transactional extractTransactionalAnnotation(javax.interceptor.InvocationContext context)

Returns:

the @Transactional annotation from either the method or class or null if none present.
