  +--oracle.ifs.beans.LibrarySession

All Implemented Interfaces:

oracle.ifs.common.CollectionResolver, IfsEventHandler, LibrarySessionInterface, oracle.ifs.common.SessionCallbackInterface, Traceable

public final class LibrarySession

extends java.lang.Object

implements LibrarySessionInterface, oracle.ifs.common.CollectionResolver, IfsEventHandler, Traceable, oracle.ifs.common.SessionCallbackInterface

A LibrarySession is used to represent a connection-based Session with the iFS server.

A LibrarySession (also known as a "session") object is created by calling the connect method on LibraryService. All other persistent objects (that is, objects that are stored in the iFS server) are created from this class.

The public methods on this class can be divided into the following categories:

• Methods to create new persistent objects. The creation methods take the form of a create[ObjectName] method, and take a definition object containing creation parameters.
• Methods to free persistent objects, or to delete and undelete PublicObjects.
• Methods to get and set administration modes for the session.
• Methods to server configuration and version information.
• Methods to manage transaction state.
• Methods to get information about the connected user.
• Methods to get Collections for certain classes of objects.
• Methods to find objects by their Identifers.
• Methods to tracing and localization.
• Methods to manage events.

                                            IfsEventHandler handler)
                                     throws IfsException

Registers the specified IfsEventHandler to receive events for all objects in the specified class.

This method allows any object implementing the IfsEventHandler interface to receive notification of events for any LibraryObject. This could be used, for example, to automatically refresh a window displaying the items in a Folder whenever the Folder's contents change.

Parameters:

co - the ClassObject of interest

includeSubclasses - whether to include current subclasses of co; if a new subclass is subsequently created, it must be explicitly registered for IfsEventHandler to receive events on LibraryObjects of that new class

handler - the IfsEventHandler

Throws:

IfsException - (IFS-11000) if the operation fails

deregisterClassEventHandler

public final void deregisterClassEventHandler(ClassObject co,
                                              boolean includeSubclasses,
                                              IfsEventHandler handler)
                                       throws IfsException

Deregisters the specified IfsEventHandler for the specified class.

Parameters:

co - the ClassObject. If null, all ClassObjects previously registered for the IfsEventHandler using registerClassEventHandler are deregistered.

includeSubclasses - whether to include current subclasses of co

handler - the IfsEventHandler. If null, all IfsEventHandlers previously registered for the ClassObject using registerClassEventHandler are deregistered.

Throws:

IfsException - (IFS-11001) if the operation fails

isConnected

public boolean isConnected()

Return connection state of this LibrarySession

Returns:

the connection state; true if connected.

getDirectoryObject

public DirectoryObject getDirectoryObject(java.lang.Long id)
                                   throws IfsException

Lookup a DirectoryObject by its id.

Parameters:

id - identifier for the object

Returns:

the DirectoryObject

Throws:

IfsException - if operation fails.

getSchemaObject

public SchemaObject getSchemaObject(java.lang.Long id)
                             throws IfsException

Lookup a SchemaObject by its id.

Parameters:

id - identifier for the object

Returns:

the SchemaObject

Throws:

IfsException - if operation fails.

getSystemObject

public SystemObject getSystemObject(java.lang.Long id)
                             throws IfsException

Lookup a SystemObject by its id.

Parameters:

id - identifier for the object

Returns:

the SystemObject

Throws:

IfsException - if operation fails.

getPublicObject

public PublicObject getPublicObject(java.lang.Long id)
                             throws IfsException

Lookup a PublicObject by its id.

Parameters:

id - identifier for the object

Returns:

the PublicObject

Throws:

IfsException - if operation fails.

getObjectsLockedForSession

public PublicObject[] getObjectsLockedForSession()
                                          throws IfsException

Gets the array of PublicObjects that the current session holds session locks on.

Returns:

the PublicObjects currently session locked by this session.

Throws:

IfsException - if operation fails.

unlockForSession

public void unlockForSession(PublicObject[] items)
                      throws IfsException

Release session locks on a set of PublicObjects. This method is convenient for releasing session locks explicitly on all objects that are locked by this session; use this method in conjunction with the getObjectsLockedForSession() method.

The objects are unlocked in a single transaction; any failure will rollback the entire operation.

Parameters:

items - the PublicObjects to be unlocked.

Throws:

IfsException - if operation fails.

getWorldDirectoryGroup

public DirectoryGroup getWorldDirectoryGroup()
                                      throws IfsException

Gets the DirectoryGroup that represents World access.

Returns:

the World group.

Throws:

IfsException - if operation fails.

grantAdministration

public void grantAdministration(DirectoryUser user)
                         throws IfsException

Grant the Administrator Mode state for the specified Directory User.

Parameters:

user - the user to receive the admin grant

Throws:

IfsException - if operation fails.

beginTransaction

public final Transaction beginTransaction()
                                   throws IfsException

Starts a writeable transaction.

a token that can be passed to either completeTransaction or abortTransaction

Throws:

IfsException - (IFS-10651) if the operation fails

public final void completeTransaction(Transaction transaction)
                               throws IfsException

Completes a transaction.

Parameters:

transaction - the transaction to complete

abortTransaction

public final void abortTransaction(Transaction transaction)
                            throws IfsException

Aborts a transaction.

Parameters:

transaction - the transaction to abort

Throws:

IfsException - (IFS-10653) if the operation fails
