Fields

· address

Summary  |  Top

   private int address

Address value

   private String nameMask

If not null, then nameMask is a host name with or without wildcards.

XXX nameMask overrides the address masks?

   private String[] nameTokens

Because the nameMask is only set in the constructor, the tokenization of it should be cached for comparison later

   private int addressMask

Bitmask telling us which parts of address are valid, if the bit is on then we match the corresponding 8 bits in address. If the bit is off then anything matches.
