All Known Implementing Classes:

CrossStoreNodeEntityState, DefaultEntityState, DetachedEntityState, NodeEntityState, RelationshipEntityState

public interface EntityState<STATE>

Interface for classes encapsulating and delegating read and write field access of an GraphBacked entity to a number of field accessors. Wraps the entity, the underlying state and also handles the creation of the state (call back).
