Class BaseOptimizedSessionPersistedObject

java.lang.Object
  org.apache.tapestry5.BaseOptimizedSessionPersistedObject

All Implemented Interfaces:

OptimizedSessionPersistedObject

Direct Known Subclasses:

public abstract class BaseOptimizedSessionPersistedObject
extends Object
implements OptimizedSessionPersistedObject

Base implementation of OptimizedSessionPersistedObject. Subclasses should invoke markDirty() after the internal state of the object changes.

Due to the concurrent nature of session attributes it's important that markDirty occurs after the object has been changed. If the change occurs before the object has been mutated it's possible that another thread may re-store the object before the changes are actually made!

Since:

5.1.1.0
