org.apache.sling.servlets.resolver.helper.WeightedResource
The WeightedResource is a Resource which is attributed with weight values to make it a Comparable to be used to build the result collection returned by {@link ResourceCollector#getServlets(Resource)}.
The order amongst WeightedResource instances is defined as follows and implemented in the {@link #compareTo(WeightedResource)} method:
1. The instance with more matching selectors ( {@link #getNumSelectors()}) is ordered before the instance with less matching selectors.
2. If the matching selectors are equal, the instance with the higher method/prefix weight ( {@link #getMethodPrefixWeight()}) is order before the instance with a lower method/prefix weight.
3. Finally, if also the method/prefix weights are equal, the instance with the lower ordinal number ( {@link #getOrdinal()} is ordered before theinstance with the higher ordinal number.
