java.lang.Object
  org.fosstrak.ale.server.readers.IdentifyThread

All Implemented Interfaces:

java.lang.Runnable

public class IdentifyThread
extends java.lang.Object
implements java.lang.Runnable

An IdentifyThread encapsulates all the methods necessary for polling the device. The identification process itself is based on the method identify() of the associated AutoIdController.
