Method Detail

getReversedDomainParts

public static List<String> getReversedDomainParts(String host,
                                                  int numParts)

Given an url host, tokenizes the host parts by dot, reverses them, and pads (with "") or truncates up to numParts pieces. Truncation happens post token reversal. This method properly accounts for two-part top-level domains as listed at http://www.surbl.org/two-level-tlds as of 05/12/2010. For example, www.twitter.co.uk will be returned as ["co.uk", "twitter", "www"].

Parameters:

host - A url host

numParts - The number of host parts to return.

Returns:

The reversed and tokenized list of host parts from host.

                            boolean reversed)
