Obtains a List containing installed instances of the providers for the requested service. The List of providers is cached for the period of time given by cachingPeriod . During this period, the same List instance is returned for the same type of provider. After this period, a new instance is constructed and returned. The returned List is immutable.

 public static  void setCachingPeriod(int seconds) 
{
        cachingPeriod = seconds * 1000L;
}

Set the period provider lists are cached. This method is only intended for testing.
