Contains persistence APIs directly accessible by users.

Class	Description
BaseContext	A common base superclass for Cayenne ObjectContext implementors.
BaseDataObject	Base implementation of DataObject, have no assumption about how data is actually stored.
Cayenne	Various utils for processing persistent objects and their properties
CayenneDataObject	Implementation of DataObject that uses Map to store object fields.
CayenneException	Deprecated. since 4.1 use CayenneRuntimeException instead
CayenneRuntimeException	A generic unchecked exception that may be thrown by Cayenne framework.
ConfigurationException	A runtime exception thrown on failures in Cayenne configuration.
DataChannel	DataChannel is an abstraction used by ObjectContexts to obtain mapping metadata and access a persistent store.
DataChannelFilter	Deprecated. since 4.1 use DataChannelQueryFilter and DataChannelSyncFilter
DataChannelFilterChain	Deprecated. since 4.1 in favor of DataChannelSyncFilterChain and DataChannelQueryFilterChain
DataChannelListener	A listener of DataChannel lifecycle events.
DataChannelQueryFilter	An interface of a filter that allows to intercept DataChannel query operations.
DataChannelQueryFilterChain	Interface for chain of query filters
DataChannelSyncCallbackAction
DataChannelSyncFilter	An interface of a filter that allows to intercept DataChannel sync operations.
DataChannelSyncFilterChain	Interface for chain of sync filters
DataObject	Defines basic methods for a persistent object in Cayenne.
DataRow	DataRow a map that holds values retrieved from the database for a given query row.
DeleteDenyException	An exception thrown during an attempt to delete an object that has a relationship to a non-null related object, that has a DENY delete rule.
EmbeddableObject
ExtendedEnumeration	An interface that Enum classes may implement to map enum instances to arbitrary DB values that do not match the enum names or positions.
Fault	Represents a placeholder for an unresolved relationship from a source object.
FaultFailureException	A runtime exception thrown when during lazy object initialization Cayenne finds that no matching row exists in the database for a given ObjectId.
HybridDataObject	This data object like CayenneDataObject uses Map to store generic attributes, only difference is that this Map will be created lazily at first write, thus reducing memory penalty if possible.
LifecycleListener	A callback interface to listen to persistent object lifecycle events.
ObjectContext	A Cayenne object facade to a persistent store.
ObjectId	A portable global identifier for persistent objects.
PersistenceState	Defines a set of object states from the point of view of persistence.
Persistent	Defines minimal API of an object that can be persisted via Cayenne.
PersistentObject	A convenience base superclass for concrete Persistent objects.
ProcedureResult<T>	Result of procedure call.
QueryResponse	Represents a result of query execution.
QueryResult<T>	Represents a collection of items which are results of a multipart query execution.
QueryResultItem<T>	Represents a single item in a multipart query execution.
ResultBatchIterator<T>	Defines API of a batch iterator over the ResultIterator returned as a result of Select queries execution.
ResultIterator<T>	Defines API of an iterator over the records returned as a result of Select queries execution.
ResultIteratorCallback<T>	A callback interface invoked on each row when iterating over ResultIterator.
Validating	Defines a number of callback methods that allow an object to be validated before safe.
ValueHolder<E>	Provides a level of indirection for property value access, most often used for deferred faulting of to-one relationships.
