SERVICE_RANKING

public static final String SERVICE_RANKING

Service property identifying a service's ranking number.

The service ranking is used by the Framework to determine the natural order of services (when used specifically with the Tracker).

The default ranking is zero (0). A service with a ranking of Integer.MAX_VALUE is very likely to be returned as the default service, whereas a service with a ranking of Integer.MIN_VALUE is very unlikely to be returned.

If the supplied property value is not of type Integer, it is deemed to have a ranking value of zero.

Hk2 manages its meta information as String, but converts to Integer for comparisons.
