Method Detail

of

public static Set<Integer> of(String s)

Parses a range of integers expressed as a string. The string can contain non-negative integers separated by commas, ranges (represented by a hyphen between two integers), and exclusions (represented by a preceding hyphen). For example, "1,2,3-20,-7,-10-15,12".

Inclusions and exclusions are performed in the order that they are seen. For example, "1-10,-2-9,3-7,-4-6"

does contain 3, because it is included by "1-10", excluded by "-2-9" and last included by "3-7". But it does not include 4.

Parameters:

s - Range set
