Class Summary

Class	Description
AbstractTokenCreator
BranchDetectingTxVerifier	Used on the master to verify that slaves are using the same logical database as the master is running.
BranchedDataMigrator
DelegateInvocationHandler<T>	InvocationHandler for dynamic proxies that delegate calls to a given backing implementation.
EnterpriseConfigurationMigrator
HaRequestType
HaRequestType210
HaSettings	Settings for High Availability mode
HighAvailabilityDiagnostics	TODO
HighAvailabilityLogger	This class logs whenever important cluster or high availability events are issued.
HighlyAvailableGraphDatabase	This has all the functionality of an embedded database, with the addition of services for handling clustering.

MasterClient214	The Master a slave should use to communicate with its master.
MasterClient310

MasterTransactionCommitProcess	Commit process on the master side in HA, where transactions either comes in from slaves committing, or gets created and committed directly on the master.
MasterUpdatePuller	Masters implementation of update puller that does nothing since master should not pull updates.
PullerFactory	Helper factory that provide more convenient way of construction and dependency management for update pulling related components
SlaveLabelTokenCreator
SlavePropertyTokenCreator
SlaveRelationshipTypeCreator
SlaveTransactionCommitProcess	Commit process on slaves in HA.
SlaveUpdatePuller	Able to pull updates from a master and apply onto this slave database.
TransactionChecksumLookup	Transaction meta data can normally be looked up using LogicalTransactionStore.getMetadataFor(long).
