Uses of MasterTxn in com.sleepycat.je.rep.impl

Methods in com.sleepycat.je.rep.impl that return types with arguments of type MasterTxn

Modifier and Type	Method and Description
Set<MasterTxn>	RepImpl.getExistingMasterTxns() Peruse the environment wide transaction table, and return a set of all existing MasterTxns.

Methods in com.sleepycat.je.rep.impl with parameters of type MasterTxn

Modifier and Type	Method and Description
void	RepImpl.postLogAbortHook(MasterTxn txn) Releases the block latch lock, if held.
void	RepImpl.postLogCommitAbortHook(MasterTxn txn) Removes any pending acknowledgments that were registered by the preLogCommitHook.
void	RepImpl.postLogCommitHook(MasterTxn txn, LogItem commitItem) It ensures that the feeder obtains the requisite number of acknowledgments required for a successful commit.
void	RepImpl.preLogAbortHook(MasterTxn txn) Invoked before aborting a MasterTxn, this happens when the master is going to be a replica because of mastership transfer.
void	RepImpl.preLogCommitHook(MasterTxn txn) This hook is used primarily to perform the final checks before allowing the commit operation to proceed.
void	RepImpl.txnBeginHook(MasterTxn txn) Ensure that a sufficient number of feeders are available before proceeding with a master transaction begin.

Uses of MasterTxn in com.sleepycat.je.rep.impl.node

Methods in com.sleepycat.je.rep.impl.node with parameters of type MasterTxn

Modifier and Type	Method and Description
void	DurabilityQuorum.ensureReplicasForCommit(MasterTxn txn, int insufficientReplicasTimeout) See if there are a sufficient number of replicas alive to support the commit for this transaction.

Uses of MasterTxn in com.sleepycat.je.rep.stream

Methods in com.sleepycat.je.rep.stream that return MasterTxn

Modifier and Type	Method and Description
MasterTxn	FeederTxns.getAckTxn(long txnId) Returns the transaction if it's waiting for acknowledgments.
MasterTxn	FeederTxns.TxnInfo.getTxn()

Methods in com.sleepycat.je.rep.stream with parameters of type MasterTxn

Modifier and Type	Method and Description
void	FeederTxns.awaitReplicaAcks(MasterTxn txn, int timeoutMs) Waits for the required number of replica acks to come through.
void	FeederTxns.setupForAcks(MasterTxn txn) Create a new TxnInfo so that transaction commit can wait on the latch it sets up.
