Class ControllerProperties

java.lang.Object
  org.fosstrak.hal.ControllerProperties

public class ControllerProperties
extends java.lang.Object

The ControllerProperties class encapsulates the methods responsible for the parameter setting. It can be seen as a helper class that frees the user from implementing the related methods and function calls in his concrete AutoIdController imlementation. As a convention the properties file associated with a certain reader has to be named according to its class name.
