Interface Summary

PObject

PObject is an interface that must be implemented by all persistent classes.

Class Summary

AbstractPObject	AbstractPObject is a base class for persistent objects that implements the PObject interface.
AbstractProxy	AbstractProxy is the base class for all proxy classes.
AbstractTypeMap	AbstractTypeMap uses a TreeMap to map internal JType values to the corresponding SQL data type for a specific database.
AccessKey	AccessKey facilitates the implementation of the private interface pattern.
AssociationMap	AssociationMap encapsulates the metadata that describes an association between two classes and includes methods to manage associations.
AttributeMap	AttributeMap encapsulates the metadata for an attribute (or field) within a class and includes methods to get and set the value of an attribute in an instance of the class.
ClassMap	ClassMap encapsulates the metadata required to persist a class and performs the actual persistence operations using pools of prepared statements created for the class.
ColumnMap	ColumnMap encapsulates the metadata for a column within a table in a persistence environment.
Criteria	Criteria encapsulates the search criteria for finding objects and provides methods for constructing a query.
DatabaseMap	DatabaseMap encapsulates the metadata which describes a database in a persistence environment and manages a pool of connections associated with the database.
DatabaseTypeMap
JTypeMap	Map Java types to canonical SQL types.
JTypes	JTypes defines constants used to encode Java types in the persistence mechanism and methods to convert between types and type names.
Link	Link is an entry in the object directory for a persistent object.
Logger	Logger handles logging for the persistence framework.
LOID	LOID is the Logical Object IDentifier for a persistent object.
MSSTypeMap	MSSTypeMap is used to map canonical SQL types to the Microsoft SQL Server data type that is most appropriate to represent the data.
MySQLTypeMap	MySQLTypeMap is used to map canonical SQL types to the MySQL data type that is most appropriate to represent the data.
OracleTypeMap	OracleTypeMap is used to map canonical SQL types to the Oracle data type that is most appropriate to represent the data.
PersistenceContext	PersistenceContext provides the interface between a client thread and the persistence framework.
PersistenceManager	PersistenceManager coordinates all persistence activity and is the public interface to the persistence framework.
PersistenceMap	PersistenceMap is the base class for all metadata maps used by the persistence manager.
PersistenceProperties	PersistenceProperties encapsulates the properties needed to configure the persistence environment and provides methods to get properties.
SQLTypes	SQLTypes defines constants used to encode SQL types in the persistence mechanism and methods to convert between types and type names.
TableMap	TableMap encapsulates the metadata that describes a table in a persistence environment.
TypeMapEntry	TypeMapEntry encapsulates a mapping from a canonical SQL type to a database specific type name.

Package com.xavax.xstore Description

This is the main package containing the XStore/J persistence framework. The goal of the framework is to isolate the programmer from the details of mapping objects to relational databases. To a programmer, the framework appears much like an object-oriented database (ODBMS). The primary components of the famework are:

• A persistence context which provides the client interface to the framework, coordinates persistence activity, and encapsulates the object directory and object cache,
• A persistence manager which loads the metadata and manages a pool of persistence contexts,
• A set of classes which encapsulate the object to relational mapping metadata,
• A set of classes which represent search criteria for ad hoc queries, and
• A set of tools for building proxy and factory classes and generating the metadata.
