Examples of com.sun.sgs.app.util.ScalableHashMap$RemoveNodesTask

com.sun.sgs.app.util.ScalableHashMap
A task that recursively removes the children and entries of a directory node by depth-first recursion. Does not remove the node itself, and makes a copy of the node's children so that the node can continue to be used. Each time the task is run it moves to the next non-empty leaf node, removes a limited number of entries and just emptied nodes, and if needed walks up the node graph to the next non-empty directory node. If there is more work to do, it reschedules the task, otherwise it removes it. This scheme insures that the number of nodes visited per run is the same as the number needed to perform a lookup, and limits the number of entries visited, all in an attempt to keep the work small enough to fit within the transaction timeout.
