executeTransaction

public <T> T executeTransaction(TransactionOptions options,
                                TransactionalTask<T> task)
                         throws TransactionException

Specified by:

executeTransaction in interface TransactionManagerService

Throws:

TransactionException

newTransactionContext

public TransactionContext newTransactionContext(TransactionOptions options)

Specified by:

newTransactionContext in interface TransactionManagerService

newClientTransactionContext

public TransactionContext newClientTransactionContext(TransactionOptions options,
                                                      UUID clientUuid)

Specified by:

newClientTransactionContext in interface TransactionManagerService

newAllowedDuringPassiveStateTransaction

public Transaction newAllowedDuringPassiveStateTransaction(TransactionOptions options)

Creates a plain transaction object which can be used while cluster state is ClusterState.PASSIVE, without wrapping it inside a TransactionContext.

A Transaction is a lower level API than TransactionContext. It's not possible to create/access transactional data structures without TransactionContext.

A Transaction object only allows starting/committing/rolling back transaction, accessing state of the transaction and adding TransactionLogRecord to the transaction.

Parameters:

options - transaction options

Returns:

a new transaction which can be used while cluster state is ClusterState.PASSIVE

init

public void init(NodeEngine nodeEngine,
                 Properties properties)

Description copied from interface: ManagedService

Initializes this service.

Specified by:

init in interface ManagedService

Parameters:

nodeEngine - the NodeEngine that this service belongs to

properties - the Properties (can be used to pass settings to the service)

reset

public void reset()

Description copied from interface: ManagedService

Resets this service back to its initial state.

TODO: what is the purpose of reset

Specified by:

reset in interface ManagedService

shutdown

public void shutdown(boolean terminate)

Description copied from interface: ManagedService

Shuts down this service.

TODO: what is the purpose of the terminate variable

Specified by:

shutdown in interface ManagedService

Parameters:

terminate - true to shut down this service

memberAdded

public void memberAdded(MembershipServiceEvent event)

Description copied from interface: MembershipAwareService

Specified by:

memberRemoved in interface MembershipAwareService

Parameters:

event - the event for an existing member leaving the cluster

memberAttributeChanged

public void memberAttributeChanged(MemberAttributeServiceEvent event)

Description copied from interface: MembershipAwareService
