      public SimpleMetadata(long version, long lastAccesstime, long maxInactiveInterval, byte[] state)
      Construct a SimpleMetadata object
      Parameters:
      version - The version of the data. A freshly created state has a version == 0
      lastAccesstime - the last access time of the state. This must be used in conjunction with getMaxInactiveInterval to determine if the state is idle enough to be removed.
      maxInactiveInterval - the maximum time that this state can be idle in the store before it can be removed.
