Interface Summary

Interface	Description
BlobHandleGenerator	Implementation of PersistentEntityStore identifies each blob by a unique blob handle of type long.
BlobVaultItem
ComparableGetter	Selector is a generic interface for property getter functions for Entity.
DiskBasedBlobVault
Entity	Entity is an object in the EntityStore.
EntityId	Each entity id consists of two parts: id of the entity type and local id within entity type.
EntityIterable	EntityIterable allows to lazily iterate over entities.
EntityIterator	EntityIterator is an iterator of EntityIterable.
EntityStore	EntityStore describes abstract named transactional Entity Store.
MetaServer
PersistentEntityStore	PersistentEntityStore is an EntityStore operating above Environment instance.
QueryCancellingPolicy	Use StoreTransaction.setQueryCancellingPolicy(QueryCancellingPolicy) to set an instance of QueryCancellingPolicy to be able to interrupt iteration over EntityIterable instances associated with the StoreTransaction.
Selector<T>	Selector is a generic interface for property getter functions.
Sequence	Sequence allows to get unique successive non-negative long numbers.
StoreTransaction	StoreTransaction is a transaction started against EntityStore using EntityStore.beginTransaction() or EntityStore.beginReadonlyTransaction() methods.
StoreTransactionalComputable<T>	A function that can pe passed to the PersistentEntityStore.computeInTransaction(StoreTransactionalComputable) or PersistentEntityStore.computeInReadonlyTransaction(StoreTransactionalComputable) to be executed and return result within a transaction.
StoreTransactionalExecutable	A function that can pe passed to the PersistentEntityStore.executeInTransaction(StoreTransactionalExecutable) or PersistentEntityStore.executeInReadonlyTransaction(StoreTransactionalExecutable)to be executed within a transaction.
