Class PartialFileHistory

  • public class PartialFileHistory
    extends java.lang.Object
    A PartialFileHistory represents a single file in a repository over a certain period of time/versions. Whenever a file is updated or deleted, a new FileVersion is added to the file history.

    A file history is identified by a unique random identifier and holds a sorted list of file versions.

    Due to cleanup mechanisms and the delta database concept, the list of file versions is not always complete. The class hence represents a part of the file history.
