getComparableForServiceRanking

public static java.lang.Comparable<java.lang.Object> getComparableForServiceRanking(java.util.Map<java.lang.String,java.lang.Object> props,
                                                                                    Order order)

Create a comparable object out of the service properties. With the result it is possible to compare service properties based on the service ranking of a service. This object acts like ServiceReference.compareTo(Object). The comparator will return the services in the given order. In ascending order the service with the lowest ranking comes first, in descending order the service with the highest ranking comes first. The latter is useful if you want to have the service returned first which is also chosen by BundleContext.getServiceReference(String)).

Parameters:

props - The service properties.

order - The order (either ascending or descending).

Returns:

A comparable for the ranking of the service
