public Object getAspectCreationMutex()

Description copied from interface: MetadataAwareAspectInstanceFactory

Get the best possible creation mutex for this factory.

Specified by:

getAspectCreationMutex in interface MetadataAwareAspectInstanceFactory

Returns:

the mutex object (may be null for no mutex to use)

getOrderForAspectClass

protected int getOrderForAspectClass(Class<?> aspectClass)

Description copied from class: SingletonAspectInstanceFactory

Determine a fallback order for the case that the aspect instance does not express an instance-specific order through implementing the Ordered interface.

The default implementation simply returns Ordered.LOWEST_PRECEDENCE.
