Hi Will,
The LdapIdentityStoreDefinition annotation and annotations like that,
function essentially as declarative Bean Factories. They are modelled after
the existing DataSourceDefinition annotation in Java EE.
The annotation can be placed on whatever class seen by CDI. When it's
encountered by the CDI extension responsible for processing it, it causes
another bean to be programmatically introduced into the CDI context with
parameters such as set on the *Definition annotation. The actual type of
the bean is left to the implementation, but it implements the IdentityStore
interface.
This can be seen when looking at the following code from the CdiExtension
class in Soteria:
Optional<LdapIdentityStoreDefinition> optionalLdapStore =
getAnnotation(
beanManager,
event.getAnnotated(),
LdapIdentityStoreDefinition.class);
if (optionalLdapStore.isPresent()) {
identityStoreBeans.add(new CdiProducer<IdentityStore>()
.scope(ApplicationScoped.class)
.beanClass(IdentityStore.class)
.types(Object.class, IdentityStore.class,
LdapIdentityStore.class)
.addToId(LdapIdentityStoreDefinition.class)
.create(e -> new LdapIdentityStore(optionalLdapStore
.get()))
);
}
So per the above code, if an "LdapIdentityStoreDefinition" annotation is
present, a Bean<T> is programmatically added, with the actual
implementation backed by
"org.glassfish.soteria.identitystores.LdapIdentityStore".
Hope this helps ;)
Kind regards,
Arjan Tijms
