Class AbstractCacheTransaction

java.lang.Object

org.infinispan.transaction.AbstractCacheTransaction

All Implemented Interfaces:

CacheTransaction

Direct Known Subclasses:

LocalTransaction, RemoteTransaction

public abstract class AbstractCacheTransaction
extends Object
implements CacheTransaction

Base class for local and remote transaction. Impl note: The aggregated modification list and lookedUpEntries are not instantiated here but in subclasses. This is done in order to take advantage of the fact that, for remote transactions we already know the size of the modifications list at creation time.

Since:

4.2
