public interface TransactionEvent
An event that describes the culmination of an entire transaction. It either describes the work
done by a committed transaction or the work abandoned by an explicit rollback or failed commit.
The actual work is represented by an ordered list of EntryEvent instances.
A TransactionListener receives an instance of this class allowing exploration of the
resultant operations. The resultant operation is the final result of, potentially, a sequence of
operations on a key such that earlier operations might be masked. For example, multiple put
operations using the same key will result in only one EntryEvent for that key.
An instance of TransactionEvent for the same transaction on the originating VM may differ from a recipient VM. The amount of variation will depend on the variation of the state of Entries on each VM. One reason for why this might occur is the different Expiration/Eviction settings of the similar Regions on different VMs.
The event lists are ordered according to the chronological order of the indiviual operations.
The EntryEvent instances always return null as their
callback argument.
