NAME

Sprog::Mixin::OutputToFH - a 'mixin' class for gears writing output to a file handle

SYNOPSIS

   use base qw(
     Sprog::Mixin::OutputToFH
     Sprog::Gear
   );
 
   sub engage {
     my($self) = @_;

DESCRIPTION

This mixin is for use by gears which need to write to a file handle (ie: files, pipes, sockets ...). It provides the appropriate links into the event loop to write using non-blocking IO.

METHODS

fh_out ( filehandle )

The gear class is responsible for opening the file handle and then passing it to this method to make it available to the other methods in this class.

data ( data )

When the gear receives a "data" message, this method will be invoked and the data will be queued to be written to the filehandle.
