public interface ConversionComparator
Optional interface to be implemented by

implementers. Language-specific conversions can cause increased overloaded
method resolution ambiguity, as many methods can become applicable because of
additional conversions. The static way of selecting the "most specific"
method will fail more often, because there will be multiple maximally
specific method with unrelated signatures. In these cases, language runtimes
can be asked to resolve the ambiguity by expressing preferences for one
conversion over the other.-
