Log::Dispatch::Handle - Object for logging to IO::Handle objects (and subclasses thereof)
use Log::Dispatch::Handle; my $handle = Log::Dispatch::Handle->new( name => 'a handle', min_level => 'emerg', handle => $io_socket_object ); $handle->log( level => 'emerg', message => 'I am the Lizard King!' );
This module supplies a very simple object for logging to some sort of handle object. Basically, anything that implements a
print() method can be passed the object constructor and it should work.
This method takes a hash of parameters. The following options are valid:
The name of the object (not the filename!). Required.
The minimum logging level this object will accept. See the Log::Dispatch documentation for more information. Required.
The maximum logging level this obejct will accept. See the Log::Dispatch documentation for more information. This is not required. By default the maximum is the highest possible level (which means functionally that the object has no maximum).
The handle object. This object must implement a
callbacks( \& or [ \&, \&, ... ] )
This parameter may be a single subroutine reference or an array reference of subroutine references. These callbacks will be called in the order they are given and passed a hash containing the following keys:
( message => $log_message, level => $log_level )
The callbacks are expected to modify the message and then return a single scalar containing that modified message. These callbacks will be called when either the
log_tomethods are called and will only be applied to a given message once.
log_message( message => $ )
Sends a message to the appropriate output. Generally this shouldn't be called directly but should be called through the
log()method (in Log::Dispatch::Output).
