Log::Agent::File::Native - low-overhead IO::File
SYNOPSIS
require Log::Agent::File::Native;
my $fh = Log::Agent::File::Native->make(*main::STDERR);
DESCRIPTION
This class is a stripped down implementation of IO::File, to avoid using the IO::* hierarchy which does not work properly for my simple
needs.
make glob
This is the creation routine. Encapsulates the glob reference so that we can use object-oriented calls on it.
print args
Prints args to the file.

Log::Agent::Channel - ancestor class for all Log::Agent channels
SYNOPSIS
@Log::Agent::Channel::XXX::ISA = qw(Log::Agent::Channel);
DESCRIPTION
The "Log::Agent::Channel" class is the root class from which all "Log::Agent" channels inherit. It is a deferred class, meaning that it
cannot be instantiated directly. All the deferred routines need to be implemented by its heirs to form a valid driver.
Internally, the various "Log::Agent::Driver" objects create "Log::Agent::Channel" instances for each logging channel defined at driver
creation time. The channels are therefore architecturally hidden within "Log::Agent", since this module only provides redefined mappings
for the various logxxx() routines (logerr(), logwarn(), logdie(), etc...).
However, this does not mean that channel classes cannot be used externally: the "Log::Agent::Logger" extension makes "Log::Agent::Channel"
objects architecturally visible, thereby offering an application-level logging API that can be redirected to various places transparently
for the application.
CHANNEL LIST
The following channels are currently made available by "Log::Agent". More channels can be defined by the "Log::Agent::Logger" extension:
Log::Agent::Channel::File
This channel writes logs to files, defined by their path or via a magical opening sequence such as "|cmd". See
Log::Agent::Channel::File.
Log::Agent::Channel::Handle
This channel writes logs to an already opened descriptor, as specified by its file handle: an IO::Handle object, or a GLOB reference
such as *FILE. See Log::Agent::Channel::Handle.
Log::Agent::Channel::Syslog
This channel redirects logs to the syslogd(8) daemon, which will then handle the dispatching to various logfiles, based on its own
configuration. See Log::Agent::Channel::Syslog.
INTERFACE
You need not read this section if you're only using "Log::Agent". However, if you wish to implement another channel, then this section
might be of interest.
The following routines are deferred and therefore need to be defined by the heir:
write($priority, $logstring)
Emit the log entry held in $logstring, at priority $priority. A trailing "
" is added to the $logstring, if needed (i.e. if the
physical entity does not do it already, like syslog does).
The $priority argument must be a valid syslog priority, i.e. one of the following strings: "emerg", "alert", "crit", "err", "warning",
"notice", "info", "debug".
The $logstring may not really be a plain string. It can actually be a Log::Agent::Message object with an overloaded stringification
routine, so the illusion should be complete.
close
Close the channel.
make
This is the creation routine. Its signature varies for each channel, naturally.
