NAME

Net::Nmsg::Output - Perl interface for nmsg outputs

SYNOPSIS

  use Net::Nmsg::Input;
  use Net::Nmsg::Output;

  my $in  = Net::Nmsg::Input->open('input.nmsg');
  my $out = Net::Nmsg::Output->open('output.nmsg');

  my $c = 0;

  while (my $msg = <$in>) {
    print "got message $c $msg\n";
    $out->write($msg);
    ++$c;
  }

  # alternatively:

  my $cb = sub {
    print "got message $c ", shift, "\n"
    $out->write($msg);
    ++$c;
  };
  $in->loop($cb);

DESCRIPTION

Net::Nmsg::Output provides the perl interface for the Net::Nmsg::XS::output extension.

CONSTRUCTORS

open($spec, %options): Creates and opens new output object. The output can be specified as a file name or handle, callback reference, or socket.
Options, where applicable, also apply to the more specific open calls detailed further below. Available options:

filter_vendor
filter_msgtype: Restricts the output to messages of the given vendor and msgtype. Both are required if filtering is desired.
source
operator
group: Set the source, operator, and group fields on outputs (nmsg only)
buffered_io: Control whether or not the output socket is buffered (default: 1).
zlibout: Enable or disable zlib compression of output (nmsg only)
rate
freq: Limit the payload output rate
bufsz: Set the buffer size for the output (the default value is based on whether the output is a file or socket)
broadcast: Set broadcast mode (socket only)
sndbuf: Set send buffer size (socket only)
endline: Set the line ending character for presentation outputs.

open_file($spec, %options): Opens an output in nmsg format, as specified by file name or file handle.
open_json($spec, %options): Opens an output in JSON format, as specified by file name or file handle.
open_sock($spec, %options): Opens an output socket as specified by "host/port" or socket handle. The host and port can also be provided as separate arguments.
open_pres($spec, %options): Opens an output in presentation format, as specified by file name or file handle. The 'filter_vendor' and 'filter_msgtype' options are required.
open_cb($callback): Opens a callback output using the provided code reference. The callback will be invoked with a Net::Nmsg::Msg reference each time a message is 'written' to the output.
