Constructor Detail

StreetNumberSet

public StreetNumberSet(String numbers)

Creates a StreetNumberSet containing the numbers indicated in the argument.

Requires:

numbers != null && numbers is a space-free comma-delimited list of zero or more non-overlapping parity ranges. a parity range is only considered overlapping if it shares elements with another range. For example 10-20,19-21 are not overlapping as one only contains even elements and the other contains odd.

A parity range is either a single nonnegative integer "n" or a hyphen-separated pair of nonnegative integers "m-n", where m and n have the same parity and m is no greater than n. A range m-n represents the set of all numbers from m to n, inclusive, which are the same parity as m and n. For instance, legal arguments include "", "5", "22,253", "3-101", and "1914-1918,1939-1945".
