For instance, moving a message // from a folder on IMAP server A to a folder on IMAP server B may // fail, because the transfer command can't be implemented efficiently // for this scenario, because it is not directly supported by the IMAP // protocol. On the other hand, moving a message from one folder to // another folder on the same IMAP server should work, because it can // be implemeted efficiently. Source and target folder may be the same // when doing a move operation. // // Transfers without the transfer command are done as follows: // // 1) Create a new content at the target folder // --> targetContent = target.XContentCreator::createNewContent(...) // 2) Transfer data from source to target content // --> props = sourceContent.execute( "getPropertyValues", ... ) // --> dataStream = sourceContent.execute( "open", ... ) // --> targetContent.execute( "setPropertyValues", props ) // 3) Insert ( commit ) the new content // --> targetContent.execute( "insert", dataStream ) // 4) For move operations only: destroy the source content // sourceContent.execute( "delete", ... ) // // This mechanism should work for all transfer operations, but // generally it's less efficient than the transfer command. Therefore, // a client that wants to transfer data should first try to execute // a transfer command at the target folder.

(e.g. One may specify the // maximum size of the HTTP-Cache) hyper SizeLimit // contains the count of subscribed contents of a folder. long SubscribedCount // contains the policy to use when synchronizing two objects. com::sun::star::ucb::SynchronizePolicy SynchronizePolicy // contains information about the target frame to use when displaying // an object.
