For PersistenceCapable classes using datastore identity most of the necessary behaviour is coded in the OIDMapping super class. TODO Split this from OIDMapping since a PCMapping may represent an application identity object instead of a datastore identity object version:    $Revision: 1.154 $ Field Summary protected  JavaTypeMapping[] javaTypeMappings      Mappings for all fields necessary to represent the id of the PC object. Constructor Summary public   PersistenceCapableMapping()      Create a new empty PersistenceCapableMapping. Method Summary public  void addJavaTypeMapping(JavaTypeMapping mapping)      public  DatastoreMapping getDataStoreMapping(int index)      Accessor for a datastore mapping. This method works through the java type mappings, and for each mapping through its datastore mappings incrementing the index with each datastore mapping. Parameters:   index - The position of the mapping. public  JavaTypeMapping[] getJavaTypeMapping()      public  int getNumberOfDatastoreFields()      Accessor for the number of datastore fields. public  Object getObject(ObjectManager om, Object rs, int[] param)      Returns a instance of a PersistenceCapable class. public  void initialize(DatastoreAdapter dba, AbstractMemberMetaData fmd, DatastoreContainerObject container, ClassLoaderResolver clr)      Initialize this JavaTypeMapping with the given DatastoreAdapter for the given FieldMetaData. public  ScalarExpression newLiteral(QueryExpression qs, Object value)      public  ScalarExpression newScalarExpression(QueryExpression qs, LogicSetExpression te)      public  void postFetch(StateManager sm)      Method executed just after a fetch of the owning object, allowing any necessary action to this field and the object stored in it. public  void postInsert(StateManager sm)      Method executed just after the insert of the owning object, allowing any necessary action to this field and the object stored in it. public  void postUpdate(StateManager sm)      Method executed just afer any update of the owning object, allowing any necessary action to this field and the object stored in it. public  void preDelete(StateManager sm)      Method executed just before the owning object is deleted, allowing tidying up of any relation information. protected  void prepareDatastoreMapping()      Method to prepare the PC mapping and add its associated datastore mappings. protected  void prepareDatastoreMapping(ClassLoaderResolver clr)      Method to prepare the PC mapping and add its associated datastore mappings. public  void setObject(ObjectManager om, Object ps, int[] param, Object value)      Method to set an object in the datastore. public  void setObject(ObjectManager om, Object ps, int[] param, Object value, StateManager ownerSM, int ownerFieldNumber)      Method to set an object reference (FK) in the datastore. Field Detail javaTypeMappings protected JavaTypeMapping[] javaTypeMappings(Code) Mappings for all fields necessary to represent the id of the PC object. Constructor Detail PersistenceCapableMapping public PersistenceCapableMapping()(Code) Create a new empty PersistenceCapableMapping. The caller must call one of the initialize methods to initialize the instance with the DatastoreAdapter and its type. Method Detail addJavaTypeMapping public void addJavaTypeMapping(JavaTypeMapping mapping)(Code) Add a new JavaTypeMapping Parameters:   mapping - the JavaTypeMapping getDataStoreMapping public DatastoreMapping getDataStoreMapping(int index)(Code) Accessor for a datastore mapping. This method works through the java type mappings, and for each mapping through its datastore mappings incrementing the index with each datastore mapping. Parameters:   index - The position of the mapping. The datastore mapping. getJavaTypeMapping public JavaTypeMapping[] getJavaTypeMapping()(Code) Accessor for the Java type mappings The Java type mappings getNumberOfDatastoreFields public int getNumberOfDatastoreFields()(Code) Accessor for the number of datastore fields. Zero datastore fields implies that the mapping uses a FK in the associated class to reference back. Number of datastore fields for this PC mapping. getObject public Object getObject(ObjectManager om, Object rs, int[] param)(Code) Returns a instance of a PersistenceCapable class. Processes a FK field and converts the id stored firstly into an OID/AID and then into the object that the FK id relates to. Parameters:   om - The Object Manager Parameters:   rs - The ResultSet Parameters:   param - Array of parameter ids in the ResultSet to retrieve The Persistence Capable object initialize public void initialize(DatastoreAdapter dba, AbstractMemberMetaData fmd, DatastoreContainerObject container, ClassLoaderResolver clr)(Code) Initialize this JavaTypeMapping with the given DatastoreAdapter for the given FieldMetaData. Parameters:   dba - The Datastore Adapter that this Mapping should use. Parameters:   fmd - FieldMetaData for the field to be mapped (if any) Parameters:   container - The datastore container storing this mapping (if any) Parameters:   clr - the ClassLoaderResolver newLiteral public ScalarExpression newLiteral(QueryExpression qs, Object value)(Code) newScalarExpression public ScalarExpression newScalarExpression(QueryExpression qs, LogicSetExpression te)(Code) postFetch public void postFetch(StateManager sm)(Code) Method executed just after a fetch of the owning object, allowing any necessary action to this field and the object stored in it. Parameters:   sm - StateManager for the owner. postInsert public void postInsert(StateManager sm)(Code) Method executed just after the insert of the owning object, allowing any necessary action to this field and the object stored in it. Parameters:   sm - StateManager for the owner postUpdate public void postUpdate(StateManager sm)(Code) Method executed just afer any update of the owning object, allowing any necessary action to this field and the object stored in it. Parameters:   sm - StateManager for the owner preDelete public void preDelete(StateManager sm)(Code) Method executed just before the owning object is deleted, allowing tidying up of any relation information. Parameters:   sm - StateManager for the owner prepareDatastoreMapping protected void prepareDatastoreMapping()(Code) Method to prepare the PC mapping and add its associated datastore mappings. prepareDatastoreMapping protected void prepareDatastoreMapping(ClassLoaderResolver clr)(Code) Method to prepare the PC mapping and add its associated datastore mappings. Parameters:   clr - The ClassLoaderResolver setObject public void setObject(ObjectManager om, Object ps, int[] param, Object value)(Code) Method to set an object in the datastore. Parameters:   om - The ObjectManager Parameters:   ps - The Prepared Statement Parameters:   param - The parameter ids in the statement Parameters:   value - The value to put in the statement at these ids throws:   NotYetFlushedException - setObject public void setObject(ObjectManager om, Object ps, int[] param, Object value, StateManager ownerSM, int ownerFieldNumber)(Code) Method to set an object reference (FK) in the datastore. Parameters:   om - The Object Manager Parameters:   ps - The Prepared Statement Parameters:   param - The parameter ids in the statement Parameters:   value - The value to put in the statement at these ids Parameters:   ownerSM - StateManager for the owner object Parameters:   ownerFieldNumber - Field number of this PC object in the owner throws:   NotYetFlushedException - Methods inherited
