Interface TransientPushResultSetDao

All Known Implementing Classes:

CacheTransientResultSetDaoImpl

public interface TransientPushResultSetDao

offer access to the underlying in-memory or pseudo-memory (serialization backed caches) storage for the transient push-resultsets. This type of push resultsets doesn't even try to make efficient access to records, they just keep them as big lists on the underlying storage. Actual implementations may decide to keep them on the heap or to use some caching technology like ehcache.
