Java Source File NameTypeComment
AnonymousFieldDescriptor.javaClass
ArgumentDescriptor.javaClass An ArgumentDescriptor contains information that defines a single argument that is passed to a procedure/function.
AttributeContainer.javaInterface This interface defines methods that are required for an object to support the nested "attribute" tag in the repository file.
AttributeDescriptorBase.javaClass Is the base class for all other attribute descriptors.
ClassDescriptor.javaClass A ClassDescriptor contains all information for mapping objects of a given class to database tables.
ClassNotPersistenceCapableException.javaClass
CollectionDescriptor.javaClass mapping Description for member fields that are Collections
Note: Be careful when use references of this class or caching instances of this class, because instances could become invalid (see MetadataManager ).
ConnectionDescriptorXmlHandler.javaClass The handler catches Parsing events raised by the xml-parser and builds up the ConnectionRepository that is used within the OJB.

TODO: Reading of metadata are split in two classes RepositoryXmlHandler and ConnectionDescriptorXmlHandler .

ConnectionPoolDescriptor.javaClass Encapsulates connection pooling and JDBC-driver configuration properties managed by org.apache.ojb.broker.metadata.JdbcConnectionDescriptor .
ConnectionRepository.javaClass
CustomAttributesTest.javaClass This TestClass tests the RepositoryPersitors facilities for reading and writing a valid repository.
DeleteProcedureDescriptor.javaClass An DeleteProcedureDescriptor contains information that is related to the procedure/function that is used to handle the deleting of existing records.
DescriptorBase.javaClass base class for all Descriptors.
DescriptorRepository.javaClass The repository containing all object mapping and manipulation information of all used persistent objects.
FieldDescriptor.javaClass A FieldDescriptor holds the mapping information for a specific member-variable of a persistent object.
FieldHelper.javaClass
FieldType.javaInterface OJB implements the mapping conventions for JDBC as specified by the JDBC 3.0 specification and this class representing the jdbc java types of the sql types mappings - e.g.
FieldTypeClasses.javaClass Encapsulates all FieldType as inner classes.
IndexDescriptor.javaClass
InsertProcedureDescriptor.javaClass An InsertProcedureDescriptor contains information that is related to the procedure/function that is used to handle the insertion of new records.
JdbcConnectionDescriptor.javaClass JdbcConnectionDescriptor describes all relevant parameters of JDBC Connections used by the PersistenceBroker.
JdbcMetadataUtils.javaClass This class provides some utility functions to OJB for working with JDBC metadata.
JdbcType.javaInterface Represents a jdbc sql type object defined by the JDBC 3.0 specification to handle data conversion (see JDBC 3.0 specification Appendix B, Data Type Conversion Tables).
JdbcTypesHelper.javaClass Helper class which provide all supported JdbcType classes (based on the java.sql.Types ) as inner classes.
MetadataConfiguration.javaInterface
MetadataException.javaClass This exception is thrown if a MetaData related problem occurs.
MetadataManager.javaClass Central class for metadata operations/manipulations - manages OJB's metadata objects, in particular: This class allows transparent flexible metadata loading/manipulation at runtime.

How to read/merge metadata
Per default OJB loads default org.apache.ojb.broker.metadata.DescriptorRepository and org.apache.ojb.broker.metadata.ConnectionRepository instances, by reading the specified repository file.

MetadataMultithreadedTest.javaClass
MetadataTest.javaClass This TestClass tests the RepositoryPersitors facilities for reading and writing a valid repository.
ObjectCacheDescriptor.javaClass Encapsulates a org.apache.ojb.broker.cache.ObjectCache implementation class and its proprietary configuration properties.
ObjectReferenceDescriptor.javaClass Describes a Field containing a reference to another class.
PersistentFieldPerfTest.javaClass This is a developer test and NOT part of the test suite.
PersistentFieldTest.javaClass Test to check the capability of the org.apache.ojb.broker.metadata.fieldaccess.PersistentField implementations.
ProcedureDescriptor.javaClass A ProcedureDescriptor contains information that is common for all types of procedures/functions that are used to handle the persistence operations.
ReadonlyTest.javaClass
ReferenceMapTest.javaClass
RepositoryElements.javaInterface This interface contains integer constants representing the elements of a DescriptorRepository.
RepositoryElementsTest.javaClass
RepositoryPersistor.javaClass This class is responsible for reading and writing DescriptorRepository objects from and to persistent media.
RepositoryPersistorTest.javaClass This TestClass tests the RepositoryPersitors facilities for reading and writing a valid repository.
RepositoryTags.javaClass this class maintains a table mapping the xml-tags used in the repository.dtd to their corresponding ids used within OJB. This table is used in
1.
RepositoryXmlHandler.javaClass The handler catches Parsing events raised by the xml-parser and builds up the DescriptorRepository that is used within the OJB PersistenceBroker System.

TODO: Reading of metadata are split in two classes RepositoryXmlHandler and ConnectionDescriptorXmlHandler .

RuntimeConfigurationTest.javaClass Test used to check if it is possible to start OJB without defined descriptors.
SequenceDescriptor.javaClass Encapsulates sequence manager configuration properties managed by org.apache.ojb.broker.metadata.JdbcConnectionDescriptor .
SuperReferenceDescriptor.javaClass This class handle inheritance as 1-1 association based on a anonymous field (no field in persistent object needed).
UpdateProcedureDescriptor.javaClass An UpdateProcedureDescriptor contains information that is related to the procedure/function that is used to handle the updating of existing records.
XmlCapable.javaInterface This interface must be implemented by classes that need to be marshalled in XML form.
