Class MapReadonlyAlphaTransaction

java.lang.Object
  org.multiverse.stms.AbstractTransaction<C,S>
      org.multiverse.stms.alpha.transactions.AbstractAlphaTransaction<ReadonlyConfiguration,org.multiverse.stms.AbstractTransactionSnapshot>
          org.multiverse.stms.alpha.transactions.readonly.AbstractReadonlyAlphaTransaction
              org.multiverse.stms.alpha.transactions.readonly.MapReadonlyAlphaTransaction

All Implemented Interfaces:

org.multiverse.api.Transaction, org.multiverse.MultiverseConstants, AlphaTransaction

public final class MapReadonlyAlphaTransaction
extends AbstractReadonlyAlphaTransaction

A readonly AlphaTransaction that does do read tracking. The advantage is that once an transactionalobject has been opened, you wont getClassMetadata load errors. Another advantage is that is can participate in retries. A disadvantage is that it it costs extra memory (because of the reads that need to be tracked).
