RESEND_PREPARE

public static final byte RESEND_PREPARE

This is sent back to callers if the global transaction is not reconised. It can happen if a prepare is sent to one set of nodes, which then fail, and a commit is sent to a "new" data owner which has not seen the prepare. Responding with this value instructs the caller to re-send the prepare. See DistributionInterceptor.visitCommitCommand() for details.

Method Detail

invalidRemoteTxReturnValue

protected Object invalidRemoteTxReturnValue()

Description copied from class: AbstractTransactionBoundaryCommand

This is what is returned to remote callers when an invalid RemoteTransaction is encountered. Can happen if a remote node propagates a transactional call to the current node, and the current node has no idea of the transaction in question. Can happen during rehashing, when ownerships are reassigned during a transactions. Returning a null usually means the transactional command succeeded.

Overrides:

invalidRemoteTxReturnValue in class AbstractTransactionBoundaryCommand

Returns:

return value to respond to a remote caller with if the transaction context is invalid.

acceptVisitor

public Object acceptVisitor(InvocationContext ctx,
                            Visitor visitor)
                     throws Throwable

Description copied from interface: VisitableCommand

Accept a visitor, and return the result of accepting this visitor.

Parameters:

ctx - invocation context

visitor - visitor to accept

Returns:

arbitrary return value

Throws:

Throwable - in the event of problems

getCommandId

public byte getCommandId()

Description copied from interface: ReplicableCommand

Used by marshallers to convert this command into an id for streaming.

Returns:

the method id of this command. This is compatible with pre-2.2.0 MethodCall ids.

toString

public String toString()

Overrides:

toString in class AbstractTransactionBoundaryCommand
