    • Method Detail

      • silverpeasId

        public String silverpeasId()
        Description copied from class: WopiFile
        Silverpeas's identifier identifies the file from point of view of Silverpeas's platform.

        In most of case, WopiFile.id() will return same identifier as WopiFile.silverpeasId() returns.

        But sometimes, when a temporary view exists for a file and that the temporary view is the content exposed for modifications, WopiFile.silverpeasId() returns the identifier of the document and WopiFile.id() returns the identifier of the view (the one used by WOPI exchanges).

        Specified by:
        silverpeasId in class WopiFile
        Returns:
        a unique identifier as string.

      • id

        public String id()
        Description copied from class: WopiFile
        A File ID is a string that represents a file being operated on via WOPI operations. A host must issue a unique ID for any file used by a WOPI client. The client will, in turn, include the file ID when making requests to the WOPI host. Thus, a host must be able to use the file ID to locate a particular file.

        A file ID must:

        • Represent a single file.
        • Be an URL-safe string because IDs are passed in URLs, principally via the WOPISrc parameter.
        • Remain the same when the file is edited.
        • Remain the same when the file is moved or renamed.
        • Remain the same when any ancestor container, including the parent container, is renamed .
        • In the case of shared files, the ID for a given file must be the same for every user that accesses the file.

        Overrides:
        id in class WopiFile
        Returns:
        a unique identifier as string.

      • owner

        public User owner()
        Description copied from class: WopiFile
