VERSION

Version 0.0.1

SYNOPSIS

    use Parse::Netstat::Search;
    use Parse::Netstat::Search::Sort;
    use Parse::Netstat qw(parse_netstat);

    my $res = parse_netstat(output => join("", `netstat -n`), tcp=>1, udp=>1, unix=>0,  flavor=>$^O);

    my $pn-search=Parse::Netstat::Search->new;

    my @found=$pn-search->search( $res );

    my $sorter = Parse::Netstat::Search::Sort->new;

    @found = $sorter->sort( \@found );

The supported sort methods are as below.

    host_f     Host, Foreign (default)
    host_l     Host, Local
    port_f     Port, Foriegn
    port_l     Port, Local
    state      State
    protocol   Protocol
    q_r        Queue, Receive
    q_s        Queue, Send
    none       No sorting is done.

These dual sort can take noticably longer than the ones above.

    host_lf    Host, Local First
    port_ff    Port, Foreign First
    port_lf    Port, Local First
    q_rf       Queue, Receive First
    q_sf       Queue, Send First

Methods

new

Initiates the object.

    my $sorter=Parse::Netstat::Search->new;

get_sort

This returns the current sort method.

    my $sort=$pnc->get_sort;

set_sort

This sets the sort method to be used and if it should be inverted.

The first argument is the sort method name and the second is a boolean on if it should be inverted or not.

Leaving either undef resets the undef value back to the default.

The supported sorting methods are as below.

    $ sorter->set_sort( $sort_method );
    if( $sorter->error ){
        warn( '"'.$sort_method.'"' is not a valid sort method );
    }
    
    # reset to defaults
    $sorter->set_sort
    
    # Set the sort method to host_f and invert.
    $sorter->set_sort( 'host_f' )

sort

Sorts the provided array from Parse::Netstat::Search.

    my @sorted=$sorter->sort( \@found );

host_sort_helper

Internal function.

Takes a host and converts it to a number.

port_sort_helper

Makes sure a port number is always returned.
