Class	Description
AtomicKVDatabase	Wrapper class that presents an AtomicKVStore view of a KVDatabase, using individual transactions for each operation.
AtomicKVStore	Extension of the KVStore interface for implementations that support atomic, batched reads and writes.
BranchedKVTransaction	A KVTransaction that is based on a snapshot from an original KVTransaction and that can, at some arbitrary later time, be merged back into a new KVTransaction from the same database, assuming no conflicting changes have occurred in the meantime.
Conflict	Represents an MVCC conflict.
DeltaKVStore	Presents a mutable view of an underlying read-only KVStore and records the mutations in memory.
MemoryAtomicKVStore	Provides a KVStore view of an underlying ConcurrentNavigableMap<byte[], byte[]> whose keys are sorted lexicographically as unsigned bytes.
MutableView	Straightforward implementation of the DeltaKVStore interface.
Mutations	Represents a set of mutations that can be applied to a KVStore.
ReadAdjustConflict	Represents an MVCC conflict in which a key that was read in one transaction was adjusted via KVStore.adjustCounter() in another, simultaneous transaction.
ReadRemoveConflict	Represents an MVCC conflict in which a key or range of keys that was read in one transaction was removed in another, simultaneous transaction.
Reads	Holds a set of reads from a KVStore.
ReadWriteConflict	Represents an MVCC conflict in which a key that was read in one transaction had its value changed in another, simultaneous transaction.
SnapshotKVDatabase	KVDatabase implementation based on an underlying AtomicKVStore using snapshot views and optimistic locking to provide concurrent transactions and linearizable ACID consistency.
SnapshotKVTransaction	SnapshotKVDatabase transaction.
TransactionConflictException	Exception thrown when a transaction fails because of an MVCC conflict.
Writes	Holds a set of writes to a KVStore.
