Implementation of IComparer<T> that can compare content negotiation header fields based on their quality values (a.k.a q-values).

See MediaTypeHeaderValueComparer for a comparer for media type q-values.

Methods

Compare(StringWithQualityHeaderValue, StringWithQualityHeaderValue)

Compares two StringWithQualityHeaderValue based on their quality value (a.k.a their "q-value"). Values with identical q-values are considered equal (i.e the result is 0) with the exception of wild-card values (i.e. a value of "*") which are considered less than non-wild-card values. This allows to sort a sequence of StringWithQualityHeaderValue following their q-values ending up with any wild-cards at the end.
