                                  DataNode node)
        Add the node into the map without update the digest.
        Parameters:
        path - the path of the node
        node - the actual node associated with this path
      • get

        DataNode get​(java.lang.String path)
        Return the data node associated with the path.
        Parameters:
        path - the path to read from
      • remove

        DataNode remove​(java.lang.String path)
        Remove the path from the internal nodes map.
        Parameters:
        path - the path to remove
        Returns:
        the node being removed
      • entrySet

        java.util.Set<java.util.Map.Entry<java.lang.String,​DataNode>> entrySet()
        Return all the entries inside this map.
      • clear

        void clear()
        Clear all the items stored inside this map.
      • size

        int size()
        Return the size of the nodes stored in this map.
      • preChange

        void preChange​(java.lang.String path,
                       DataNode node)
