Class NikeFS2SwapFileManager

java.lang.Object
  org.deckfour.xes.nikefs2.NikeFS2SwapFileManager

public class NikeFS2SwapFileManager
extends Object

This class provides static facilities to acquire and manage temporary swap files. It is ensured, that acquired swap files will be removed after they are no longer used on a best-effort basis. On Unix systems, this is usually guaranteed after JVM shutdown. Especially on the Win32 platform, this class implements a workaround which will guarantee the deletion of swap files upon the next startup.
