Class RangeDouble

java.lang.Object

org.britastro.grelf.RangeDouble

public class RangeDouble
extends java.lang.Object

Convenience record for holding a pair of doubles indicating the low and high ends of a range. NB: This was intended to be written using generics but (a) base types cannot be used as T in Range<T> and (b) surprisingly, java.lang.Number does not implement Comparable. Range<T extends Number> becomes too cumbersome to write and to use.
