Method Details

get

<E extends Entity<E>> E get(@NonNull
 Entity.Id<E> id,
 @NonNull
 @NonNull Function<Entity.Id<E>,E> loader)

peek

<E extends Entity<E>> Optional<E> peek(@NonNull
 Entity.Id<E> id)

snapshot

<E extends Entity<E>> List<E> snapshot(@NonNull
 @NonNull Class<E> entityType)

Returns a immutable copy of the entities of entityType type that are in the transaction L1 cache.

entities

<E extends Entity<E>> Map<Entity.Id<E>,E> entities(@NonNull
 @NonNull Class<E> entityType)

Returns a unmodifiable map containing the entities of entityType type that are in the transaction L1 cache. The returned map is a unmodifiable live view of transaction L1 cache; changes to second affect the first. To avoid an ConcurrentModificationException exception when iterating and simultaneous modification of the transaction L1 cache, you may need to make a copy.

put

<E extends Entity<E>> void put(@NonNull
 E e)

putEmpty

<E extends Entity<E>> void putEmpty(@NonNull
 Entity.Id<E> id)

containsKey

<E extends Entity<E>> boolean containsKey(@NonNull
 Entity.Id<E> id)

empty

static FirstLevelCache empty()

create

static FirstLevelCache create()
