Class Summary

Class	Description
Base64Codec	Provides Base64 encoding and decoding as defined by RFC 2045.
ConversionUtil	A collection of static conversion utility methods.
DeepMergeOperation	An operation that merges changes from an object graph, whose objects are registered in some ObjectContext, to peer objects in an ObjectConext that is a child of that context.
DeleteRuleUpdater	DeleteRuleUpdater is responsible for auto-setting delete rules for object relationships
EqualsBuilder	Assists in implementing Object.equals(Object) methods.
EventUtil	Contains access stack events related utility methods.
GenericQueryResult<T>	Generic implementation of QueryResult using List as QueryResultItem storage.
GenericResponse	A simple serializable implementation of QueryResponse.
HashCodeBuilder	Assists in implementing Object.hashCode() methods.
IDUtil	helper class to generate pseudo-GUID sequences.
IncrementalListResponse	A QueryResponse that contains a sublist of the query result.
IndexPropertyList	A List implementation that would maintain its internal ordering based on some object numeric "index" property.
Invocation	Invocation represents a dynamic method invocation bound to a specific target.
ListResponse	A QueryResponse optimized to hold a single object or data row list.
LocalizedStringsHandler	Provides access to various modeler resources (mainly strings) obtained via a ResourceBundle.
MemoryBlob	A Blob implementation that stores content in memory.
MemoryClob	A Clob implementation that stores contents in memory.
ObjectContextGraphAction	A base implementation of a helper class to handle ObjectContext.propertyChanged(org.apache.cayenne.Persistent, String, Object, Object) processing on behalf of an ObjectContext.
ObjectContextQueryAction	A helper class that implements DataChannel.onQuery(ObjectContext, Query) logic on behalf of an ObjectContext.
ObjectDetachOperation	An operation that creates a subgraph of detached objects, using the PrefetchTree to delineate the graph boundaries.
PersistentObjectHolder	A ValueHolder implementation that holds a single Persistent object related to an object used to initialize PersistentObjectHolder.
PersistentObjectList	A list of persistent objects lazily resolved on the first access.
PersistentObjectMap
PersistentObjectSet
ProcedureResultBuilder<T>
QueryResultBuilder
RelationshipFault	An abstract superclass of lazily faulted to-one and to-many relationships.
ResultIteratorIterator<T>
ShallowMergeOperation	An operation that merges changes from a single object registered in some ObjectContext, to a peer object in an ObjectConext that is a child of that context.
ToStringBuilder	A utility class to simplify implementation of Object toString methods.
Util	Contains various unorganized static utility methods used across Cayenne.
XMLEncoder	A helper class to encode objects to XML.
