Package org.apache.openjpa.meta

OpenJPA Metadata

This package provides an extendable framework for parsing and caching persistence metadata. The metadata can be accessed at both enhancement time and at runtime.

Interface Summary

Interface	Description
AbstractCFMetaDataFactory.Parser	Internal parser interface.
AbstractCFMetaDataFactory.Serializer	Internal serializer interface.
MetaDataContext	Allows us to access configuration through metadata in a generic way.
MetaDataDefaults	Populates new metadata with default values.
MetaDataFactory	The MetaDataRepository uses implementations of this interface to load and store metadata.
MetaDataModes	Mode constants used to track the initialization status of metadata.
Order	Order a field.
SequenceMetaData.SequenceFactory	Allow facades to supply adapters from a spec sequence type to the OpenJPA sequence type.
ValueMetaData	Holds metadata on a value; this could be a field value, key value, or element value.
XMLMetaData	Describe metadata about an xml type.

Class Summary

Class	Description
AbstractCFMetaDataFactory	Base class for factory implementations built around XML metadata files in the common format.
AbstractMetaDataDefaults	Abstract implementation provides a set of generic utilities for detecting persistence meta-data of Field/Member.
AbstractMetaDataFactory	Abstract MetaDataFactory that provides default implementations of many methods.
AccessCode	Represents access styles for members of a class and field through a 5-bit integer.
ClassMetaData	Contains metadata about a persistent type.
DelegatingMetaDataFactory	Base class for factory instances that use a delegate.
Extensions	Vendor extensions.

MultiQueryMetaData	Extends QueryMetaData to allow multiple result class or mapping names.
MultiQueryMetaData.Parameter	A parameter
NoneMetaDataFactory	No-op metadata I/O to prevent attempts to load other classes.
NonPersistentMetaData	Metadata about a persistence-aware type.
QueryMetaData	Holds metadata about named queries.
SequenceMetaData	Metadata about a named sequence.
UpdateStrategies	Strategies for persistent value updates.
ValueMetaDataImpl	Default ValueMetaData implementation.
ValueStrategies	Strategies for persistent value generation.
XMLClassMetaData
XMLFieldMetaData	Contains metadata about an xml element or attribute
