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.

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 =item 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)

endline

Set the line ending character for presentation outputs.

open_nmsg($spec, %options)

Opens an output in nmsg format, as specified by file name, file handle, socket specification, or socket handle.

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.
