Class ComparablePair<F extends Comparable<F>,S>

java.lang.Object
  com.groiss.ds.Pair<F,S>
      com.groiss.ds.ComparablePair<F,S>

All Implemented Interfaces:

KeyValuePair<F,S>, Serializable, Comparable<ComparablePair<F,?>>

public class ComparablePair<F extends Comparable<F>,S>
extends Pair<F,S>
implements Comparable<ComparablePair<F,?>>

The comparable pair represents a pair of a key and a value. The key is used for comparing, the value is used for the toString method. This is useful if you want to sort a list be the keys and show the values. For example: new ComparablePair(dateval, CalUtil.showDate(dateval))
