Interface Sorter

@Contract
public interface Sorter

Contract for sorting descriptors for run level services. It should be noted that sorting the handles in a multi-threaded environment is a heuristic in any case, as the threads are scheduled randomly. Sorting can only be guaranteed in a single threaded or no-threaded case.

Method Detail

List<ServiceHandle<?>> sort(List<ServiceHandle<?>> descriptors)

Parameters:

descriptors - the list descriptors to be sorted

Returns:

The list as sorted. If this returns null then the list as passed in will be used. If any of the service handles returned are not in the run-level being processed they will be ignored. This list may add or remove handles to the list
