org.freedesktop.Telepathy.Connection.Interface.FileSharing.DRAFT

Implementations of this interface must also implement: 

  * org.freedesktop.Telepathy.Connection

An interface on connections to support protocols which allow users to designate a set of files as available for retrieval by other users of their choosing. Other features specified by this interface include file metadata, revisions, and download mirrors.


Methods:

CreateFileListing ( s: Title, s: PubSubNodeName, s: Description)-> b

In order to be able to publish a file on a PubSub server one should have a PubSub node. Here the Discription parameter is optional. Returns whether the FileListing was created ('true') or not ('false').

Parameters

Title - s This will be the title of the pubsub node.

PubSubNodeName - s This is how the repository of the user will be referenced.

Discription - s This is optional and can be use to give the discription of the FileListing that is being created.


Returns

Returns 'true' if the FileListing was created and 'false' if it was not.


Possible Error

org.freedesktop.Telepathy.Error.Disconnected The connection is not currently connected and cannot be used. This error may also be raised when operations are performed on a Connection for which StatusChanged has signalled status Disconnected for reason None.






AddSubSection ( s: Title, s: PubSubNodeName, s: SubSectionPubSubNodeName, s: Description) -> b

This method is called in order to add a SubSection to an already existing PubSubNode. This method returns whether the creation of the SubSection was successful ('true') or not ('false').

Parameters

Title - s This will be the title of the subsection.

PubSubNodeName - s This is how the repository of the user will be referenced.

SubSectionPubSubNodeName - s This is how the SubSection will be referenced.

Discription - s This is optional and can be use to give the discription of the SubSection that is being created.


Returns

Returns 'true' if the SubSection was created and 'false' if it was not.


Possible Error

org.freedesktop.Telepathy.Error.Disconnected The connection is not currently connected and cannot be used. This error may also be raised when operations are performed on a Connection for which StatusChanged has signalled status Disconnected for reason None.

org.freedesktop.Telepathy.Error.InvalidHandle 

   		The PubSubNodeName specified is unknown on this channel or connection. (generic description)

org.freedesktop.Telepathy.Error.PermissionDenied 

   		The user is not permitted to perform the requested operation. (generic description)





SuscribeList ( s: PubSubNodeToSubscribe, s: SubscriptionType, s: SubscriptionDepth) -> b

This method is called when one wants to suscribe to a FileList. This method returns whether the subscription was successful ('true') or not ('false').

Parameters

PubSubNodeToSubscribe - s This is the PubSub node user want to subscibe.

SubscriptionType - s This gives the subscription type.

SubscriptionDepth - s Since a pubsub FileListing might have many SubSections,therefore this parameter gives the depth a user want to subscribe to.


Returns

Returns 'true' if the SubSection was created and 'false' if it was not.


Possible Error

org.freedesktop.Telepathy.Error.Disconnected The connection is not currently connected and cannot be used. This error may also be raised when operations are performed on a Connection for which StatusChanged has signalled status Disconnected for reason None.

org.freedesktop.Telepathy.Error.InvalidHandle 

   		The PubSubNodeToSubscribe specified is unknown on this channel or connection. (generic description)




PublishFile ( s: PubSubNodeToAddFile, s: Filename, q: ItemId, as: Metadata, s: Mirrors) -> b

This method is called in order to to add a file to the list of published files. This method returns whether the file was published successfully ('true') or not ('false').

Parameters

PubSubNodeToAddFile - s This is the PubSub node user want to publish file to.

Filename - s This is the FileName user want to publish.

ItemId - q This Id is used to create more than one version of the same file.

Metadata - as This list all the metadata about the file which includes Size,Modified,CheckSum,Ckecksumtype and Mime.

Mirrors - s This list the mirrors from where the file can be fetched.


Return Returns 'true' if the FileName was published and 'false' if it was not.


Possible Error

org.freedesktop.Telepathy.Error.Disconnected The connection is not currently connected and cannot be used. This error may also be raised when operations are performed on a Connection for which StatusChanged has signalled status Disconnected for reason None.

org.freedesktop.Telepathy.Error.InvalidHandle 

   		The PubSubNodeToAddFile specified is unknown on this channel or connection. (generic description)

org.freedesktop.Telepathy.Error.PermissionDenied The user is not permitted to perform the requested operation. (generic description)




DeleteRevision ( s: PubSubNode, q: FileItemId) -> b

This method is called in order to delete a revision from the list of published files on a PubSubNode. This method returns whether the file was deleted successfully ('true') or not ('false').


Parameters

PubSubNode - s This is the pubsub node which is holding the file with the ItemId equal to FileItemId

FileItemId - q This is the ItemId of the FileName that has to be deleted


Return Returns 'true' if the FileItemId was deleted and 'false' if it was not.


Possible Error

org.freedesktop.Telepathy.Error.Disconnected The connection is not currently connected and cannot be used. This error may also be raised when operations are performed on a Connection for which StatusChanged has signalled status Disconnected for reason None.

org.freedesktop.Telepathy.Error.InvalidHandle 

   		The PubSubNode specified is unknown on this channel or connection. (generic description)

org.freedesktop.Telepathy.Error.PermissionDenied The user is not permitted to perform the requested operation. (generic description)




MakeRevision ( s: PubSubNodeHostingFile, s: Filename, q: ItemId, as: Metadata, s: Mirrors) -> b

This method is called in order to make a revision to an existing file on a PubSubNode. Use a different ItemId than the original file. This method returns whether the file was revised successfully ('true') or not ('false').


Parameters

PubSubNodeHostingFile - s This is the PubSub node user want to publish file to.

Filename - s This is the FileName user want to publish.

ItemId - q This Id is used to create more than one version of the same file.

SetPermissions ( s: PubSubNode, s: Jid, s: Affilation) -> Nothing

This method is called in order to set permissions for users regarding a PubSubNode. This method returns whether the file was revised successfully ('true') or not ('false').


Parameter

PubSubNode - s This is the PubSub node user want to change permission of.

GetRepo( s: PubSubNode) -> as

This method is called to request the Repo hosted on the PubSubNode .

Parameter

PubSubNode - s The PubSub node on which the file repository is hosted.


Return Returns an array of strings


Possible Error

org.freedesktop.Telepathy.Error.Disconnected The connection is not currently connected and cannot be used. This error may also be raised when operations are performed on a Connection for which StatusChanged has signalled status Disconnected for reason None.

   		The PubSubNode specified is unknown on this channel or connection. (generic description)





RequestFile() -> nothing

In order to request for a file to be sent one must request a FileSharing channel for the mirror hosting the file including the following mandatory properties (Protocol, FileId). After this RequestFile is called to to configure the socket that will be used to complete this operation.




Signals :

NotificationChange( s: PubSubNodeModified, s: CollectionModified, s: Title, as: Metadata, s: Mirror)

This signal is sent to every user which is subscribed to the PubSubNode in which the change has been made.

CollectionModified - s This is collection on PubSub node which has been change

Title - s This is the Title of the collection which has been modified

Metadata - as This is the Metadata of the file which has been added/deleted

Mirror - s Mirror of the modified file.

Metadata ( u: Size, s: Modified, s: CheckSum, s: Checksumtype, s: Mime )

This represents all the information needed about the file.
