Method Detail

getPersistentEntity

public Optional<PersistentEntity<?,? extends PersistentProperty<?>>> getPersistentEntity(Class<?> type)

Returns the PersistentEntity for the given type. Will consider all MappingContexts registered but return Optional#empty() in case none of the registered ones already have a PersistentEntity registered for the given type.

Parameters:

type - can be null.

Returns:

getRequiredPersistentEntity

public PersistentEntity<?,? extends PersistentProperty<?>> getRequiredPersistentEntity(Class<?> type)

Returns the PersistentEntity for the given type. Will consider all MappingContexts registered but throw an IllegalArgumentException in case none of the registered ones already have a PersistentEntity registered for the given type.

Parameters:

type - must not be null.

Returns:

the PersistentEntity for the given domain type.

Throws:

IllegalArgumentException - in case no PersistentEntity can be found for the given type.

getManagedTypes

public Streamable<TypeInformation<?>> getManagedTypes()

Returns all TypeInformation exposed by the registered MappingContexts.

Returns:

iterator
