Method Details

resolveAssociation

default @Nullable org.jmolecules.ddd.types.Association<T,ID> resolveAssociation()

Resolves the underlying URI into an Association, potentially applying the configured identifier extractor.

Returns:

can be null.

resolveRequiredAssociation

default org.jmolecules.ddd.types.Association<T,ID> resolveRequiredAssociation()

Resolves the underlying URI into an Association, potentially applying the configured identifier extractor.

Returns:

will never be null.

Throws:

IllegalStateException - in case the value resolved is null.

withIdSource

AssociationAggregateReference<T,ID> withIdSource(Function<UriComponents,Object> extractor)

Description copied from interface: AggregateReference

Creates a new AggregateReference resolving the identifier source value from the given UriComponents.

Specified by:

withIdSource in interface AggregateReference<T extends org.jmolecules.ddd.types.AggregateRoot<T,ID>,ID extends org.jmolecules.ddd.types.Identifier>

Parameters:

extractor - must not be null.

Returns:

will never be null.
