Package com.jcorporate.expresso.core.dataobjects

Interface Summary

ContextNested	Context nested represents any object that can be retrieved or set to any specific data context.
DataExecutorInterface	This class' job is to provide an interface between DataObjects and the underlying data source.
DataField	This class represents a single field of data that is stored within the data object.
DataFieldMetaData	This interface will eventually have the same public functionality as DBField.
DataObject	This interface represents the basic needs of a dataobject, namely to add, update and delete itself, set it's own fields, and deal with things accordingly It is currently VERY crude and definitely considered ALPHA code at this time.
DataObjectMetaData	This interface contains the "definition" of the DBObject, while the DBObject itself contains only the data itself.
DataQueryInterface	This interface provides a standard interface to deal with parts that operate and return multiple DataObjects.
Defineable	Interface for providing auto-definition of DataObjects.
Mappable	Objects that implement this interface are claiming that there is a one-to-one relation between one field value and a key field value.
NestableDataObject	Nestable indicates that the derived class includes nested data objects.
Securable	Interface to described a database object that is subject to security constraints.

Class Summary

BaseDataObject	A base class that provides some functionality for all Data Objects
DataObjectFactory	Constructs 'often' DataObjects based upon standard order of initialization and the interfaces it implements.
DataTransferObject	Basic HashMap wrapper for the Data Transfer Object pattern.
DefaultDataField	Default implementation of the DataField interface.
PersistenceManager	This is the persistence manager class.
QueryAttributes	This object contains miscellaneous values that allow us to set various query attributes
SynchronizedDataObject	This class provides a threadsafe access to a dataobject.

Exception Summary

DataException	Base class exception for the dataobjects framework.
DuplicateKeyException	Exception that gets thrown when there's a duplicate key in the table.
