public interface SessionData
A container for data that is specific to a repository system session. Both components within the repository system and clients of the system may use this storage to associate arbitrary data with a session. Unlike a cache, this session data is not subject to purging. For this same reason, session data should also not be abused as a cache (i.e. for storing values that can be re-calculated) to avoid memory exhaustion. Note: Actual implementations must be thread-safe.
