NAME
Net::IANA::Registry - optimized representation of IANA's port number registry
SYNOPSIS
use Net::IANA::Registry;
my $registry = Net::IANA::Registry->new();
$registry->last_updated(); # returns '2003-06-25'
$registry->load(); # returns an arrayref of port objects
# returns a new registry module as a string
$registry->generate_new_registry_module('MyRegistry');
$registry->sep(); # returns '/' on UNIX os's
$registry->get_registry; # returns a new registry as a string
$registry->install_new_registry(); # installs a new default registry
print "There is a newer registry available from IANA\n" if
$registry->expired(), "\n";
DESCRIPTION
Net::IANA::PortNumbers uses the official IANA port number registry at the protocol/number assignments directory located at:
http://www.iana.org/assignments/port-numbers
This module represents an optimized, pipe-delimited representation of IANA's port number registry.
METHODS
new
Constructor. Returns a registry object. Accepts no arguments.
last_updated
This object method takes no arguments. Net::IANA::PortNumbers' internal database is primed from the IANA port registry. This method returns the date that the IANA port registry stated that it was last updated. Note that this is not necessarily the same date that Net::IANA::PortNumbers distribution was last updated.
sep
Returns the filesystem path separator for the current OS. Takes no arguments. On UNIX this would return '/'.
load
Returns an arrayref of port objects. Takes no arguments.
generate_new_registry_module
Generates a new registry module, based on the data from a presumably newer version of the ports file. Takes one mandatory argument: the package name that the new registry module should use. Returns the new module registry as a string. The new module can be used with the Net::IANA::PortNumbers constructor, i.e.: my $iana = Net::IANA::PortNumbers(MyRegistry->new());
expired
Determines if a newer port list registry is available from IANA. Returns 0 if your registry is the latest available, otherwise returns 0. Takes no args.
get_registry
Goes out and retrieves a new registry "over the wire". Returns the new registry as a string. Takes no arguments.
install_new_registry
Goes out and retrieves a new registry "over the wire", via get_registry(), and then installs the new default registry. You probably want to do this as root if you want it to be installed system-wide. Takes no arguments. Be advised that this new registry will be over-written during re-installations of this distribution. If you don't want this behavior then generate_new_registry_module, save the returned string to disk as the new registry module, and reference it in the Net::IANA::PortNumbers constructor.
