NAME

Net::Silk::ProtoPort - SiLK protocol/port pair

SYNOPSIS

use Net::Silk::ProtoPort;

my $pp1 = Net::Silk::ProtoPort(6, 22);
my $pp2 = Net::Silk::ProtoPort("6:443");

$pp1 < $pp2; # true

print "proto: ", $pp1->proto, "\n";
print " port: ", $pp1->port, "\n";

DESCRIPTION

Net::Silk::ProtoPort objects represent a protocol/port pair which can be used as a key (as opposed to an IP address) in Net::Silk::Pmap files.

METHODS

new($spec)

new($proto, $port)

Returns a new Net::Silk::ProtoPort object. The protocol and port can be provided directly as two arguments, or as an array reference containing the pair, or as a string with a non-digit separator such as "proto:port".

proto()

Return or set the protocol number.

port()

Return or set the port number.

copy()

Return a copy of this object. This method is tied to the = operator.

str()

Return a string representation "port:proto". This method is tied to the "" operator.

num() Return an integer representation of this proto/port pair.

distance($other)

Return an integer representing the absolute value of the distance between this protoport and another.

TIED ARRAY

The Net::Silk::ProtoPort object can be treated as an array, such that $pp->[0], $pp->[1], and @$pp work as expected.

OPERATORS

The following operators are overloaded and work with Net::Silk::ProtoPort objects:

""            bool
+=            =
+             @{}
-=
-
<=>           cmp
>             gt
<             lt
>=            ge
<=            le
==            eq
!=            ne
