@Beta
public final class CommitLocalTransactionRequest
extends AbstractLocalTransactionRequest<CommitLocalTransactionRequest>

Request to commit a local transaction. Since local transactions do not introduce state on the backend until they are ready, this message carries a complete set of modifications.

Method Detail

getDelayedFailure

public Optional<Exception> getDelayedFailure()

Return the delayed error detected on the frontend. If this error is present, it will be reported as the result of the first step of the commit process.

Returns:

Delayed failure, if present.

getModification

public DataTreeModification getModification()

isCoordinated

public boolean isCoordinated()

Indicate if this is a coordinated, multi-backend request. If this method returns true, the backend must act as a cohort participating in the three-phase commit (3PC) protocol to commit this transaction. If this method returns false, the backend should proceed to commit the transaction and respond once the commit completes or fails to complete.

Returns:

Indication of coordinated commit.

addToStringAttributes

protected MoreObjects.ToStringHelper addToStringAttributes(MoreObjects.ToStringHelper toStringHelper)

Description copied from class: Message

Add attributes to the output of Message.toString(). Subclasses wanting to contribute additional information should override this method. Any null attributes will be omitted from the output.

Overrides:

addToStringAttributes in class Request<TransactionIdentifier,CommitLocalTransactionRequest>

Parameters:

toStringHelper - a MoreObjects.ToStringHelper instance

Returns:

The MoreObjects.ToStringHelper passed in as argument
