Interface ProcedureTransaction

public interface ProcedureTransaction

ProcedureTransaction allows to mark a transaction for termination, this will make it so that it can not commit.

Method Summary

Modifier and Type	Method and Description
void	failure() Marks this transaction as failed, which means that it will unconditionally be rolled back when Transaction.close() is called.
void	terminate() Marks this transaction as terminated, which means that it will be, much like in the case of failure, unconditionally rolled back when Transaction.close() is called.

Method Detail

terminate

void terminate()

Marks this transaction as terminated, which means that it will be, much like in the case of failure, unconditionally rolled back when Transaction.close() is called. Once this method has been invoked, it doesn't matter if Transaction.success() is invoked afterwards -- the transaction will still be rolled back. Additionally, terminating a transaction causes all subsequent operations carried out within that transaction to throw a TransactionTerminatedException in the owning thread. Note that, unlike the other transaction operations, this method can be called from threads other than the owning thread of the transaction. When this method is called from a different thread, it signals the owning thread to terminate the transaction and returns immediately. Calling this method on an already closed transaction has no effect.

failure

void failure()

Marks this transaction as failed, which means that it will unconditionally be rolled back when Transaction.close() is called. Once this method has been invoked, it doesn't matter if Transaction.success() is invoked afterwards -- the transaction will still be rolled back. This method is not thread safe.
