  1. abstract class CachedFileStorage extends Thread

    Mutable storage of immutable xml trees.

    Mutable storage of immutable xml trees. Everything is kept in memory, with a thread periodically checking for changes and writing to file.

    To ensure atomicity, two files are used, filename1 and '$'+filename1. The implementation switches between the two, deleting the older one after a complete dump of the database has been written.

  2. abstract class Index[A] extends (Node) ⇒ A

    an Index returns some unique key that is part of a node

  3. class SetStorage extends CachedFileStorage

    A persistent store with set semantics.

    A persistent store with set semantics. This class allows to add and remove trees, but never contains two structurally equal trees.
