of

public static Asn of(Long value)

of

parse

public static Asn parse(String text)

Parses a String into an Asn. The representation formats that are supported are asplain, asdot+ and asdot as defined in RFC5396.

Parameters:

text - a string of an AS number e.g. "AS123", "AS0.123", "123" e.t.c.

Returns:

a new Asn

Throws:

IllegalArgumentException - if the string cannot be parsed
