NAME

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

CONTENTS

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($spec, %options) Opens an output in nmsg format, as specified by file name, or file handle.
open_sock($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.
