## Interface OptimizedSessionPersistedObject

- All Known Implementing Classes:
    AlertStorage, BaseOptimizedSessionPersistedObject, DefaultTreeExpansionModel, DefaultTreeSelectionModel, GridPaginationModelImpl, ValidationTrackerImpl

      public interface OptimizedSessionPersistedObject

  An optional interface implemented by objects that are persisted in the `Session`. At the end of each request, any objects read from the session are re-stored into the session, to ensure that in-memory changes are flushed to other persistent session stores (e.g. RDBMS, servers in a cluster, etc). Objects that implement this interface are expected to track when they are dirty (have pending changes), so that the save back into the session can be avoided when not necessary.

  This method is accessed concurrently.

  Since:
    5.1.1.0
