- Classes in org.apache.cayenne.access used by org.apache.cayenne.access
  Class and Description
  DataContext The most common implementation of `ObjectContext`.
  DataContextDelegate Defines API for a DataContext "delegate" - an object that is temporarily passed control by DataContext at some critical points in the normal flow of execution.
  DataDomain DataDomain performs query routing functions in Cayenne.
  DataNode An abstraction of a single physical data storage.
  DataPort An engine to port data between two DataNodes.
  DataPortDelegate Interface for callback and delegate methods allowing implementing classes to control various aspects of data porting via DataPort.
  DataRowStore A fixed size cache of DataRows keyed by ObjectId.
  DbLoaderDelegate DbLoaderDelegate defines API that allows to control the behavior of DbLoader during the database reverse-engineering.
  DomainStoppedException An exception thrown on attempts to access a DataDomain after it was explicitly shut down by the user.
  ObjectMapRetainStrategy A strategy for retaining objects in `ObjectStore`.
  ObjectStore ObjectStore stores objects using their ObjectId as a key.
  OperationHints Defines API that allows QueryEngine to obtain information about query execution strategy.
  OperationObserver Defines a set of callback methods that allow `QueryEngine` to pass back query results and notify caller about exceptions.
  QueryEngine Defines methods used to run Cayenne queries.
  ResultIterator Defines API of an iterator over the records returned as a result of SelectQuery execution.
  Transaction A Cayenne transaction.
  TransactionDelegate Defines callback methods for tracking and customizing Transactions execution.
