Examples of PairOfStringFloat

edu.umd.cloud9.io.pair.PairOfStringFloat
WritableComparable representing a pair consisting of a String and a float. The elements in the pair are referred to as the left and right elements. The natural sort order is: first by the left element, and then by the right element. @author Ferhan Ture
