Method Detail

getDSUserSession

public DS_UserSession getDSUserSession(UserRecord ur)

Returns a previously serialized object or a new one if none exists. When userID is "guest" the user session returned is a newly constructed one.

Specified by:

getDSUserSession in interface DS_PersistenceScheme

createServiceUserSession

public UserSession createServiceUserSession(UserRecord ur)

Description copied from class: PersistenceScheme_JDBC_Impl

Returns a new instance of the service UserSession implementation.

Specified by:

createServiceUserSession in class PersistenceScheme_JDBC_Impl

getPutSessionProcedure

public java.lang.String getPutSessionProcedure()

Returns the name of the procedure to obtain a session.

Specified by:

getPutSessionProcedure in class PersistenceScheme_JDBC_Impl

getSessionTableName

public java.lang.String getSessionTableName()

Description copied from class: PersistenceScheme_JDBC_Impl

Returns the name of the table that stores user sessions.

Specified by:

getSessionTableName in class PersistenceScheme_JDBC_Impl

saveDSUserSession

public void saveDSUserSession(DS_UserSession session)

Serializes the object in a file and keep track of it. When userID is "guest" the user session the user session is not saved.

Specified by:

saveDSUserSession in interface DS_PersistenceScheme

getCustomizedDiagram

public CustomizedDiagram getCustomizedDiagram(UserRecord ur,
                                              int diagram_id)

Get a CustomizedDiagram from the persistence storage. Returns always the latest version of CustomizedDiagram

Specified by:

getCustomizedDiagram in interface DS_PersistenceScheme

createCustomizedDiagram

public int createCustomizedDiagram(UserRecord ur,
                                   java.lang.String name,
                                   CustomizedDiagram cd,
                                   java.lang.String description)
                            throws BadPersistentID

Create customized diagram in persistent storage.

Specified by:

createCustomizedDiagram in interface DS_PersistenceScheme

Parameters:

name - name for this diagram.

cd - The customized diagram to be stored.

description - The customized diagram description to be stored.

Throws:

BadPersistentID - Thrown when the underlying persistence storage mechanism cannot handle such a persistent identifier (possible causes: invalid character, null or empty value, already allocated ID).

updateCustomizedDiagram

public void updateCustomizedDiagram(UserRecord ur,
                                    int diagram_id,
                                    CustomizedDiagram cd,
                                    java.lang.String description)
                             throws BadPersistentID

Update customized diagram in persistent storage.

updateCustomizedDiagram in interface DS_PersistenceScheme

Parameters:

diagram_id - unique diagram identifier.

cd - The customized diagram to be stored.

description - The customized diagram description to be stored.

Throws:

BadPersistentID - Thrown when the underlying persistence storage mechanism cannot handle such a persistent identifier (possible causes: invalid character, null or empty value, ID does not exist).

getLibraryObjectInfo

public LibraryObjectInfo getLibraryObjectInfo(int kind,
