NAME
Log::Dispatch::File - Object that accepts messages and does nothingSYNOPSIS
use Log::Dispatch::Null;
my $null = Log::Dispatch::Null->new( name => 'null', min_level => 'info' );
$null->log( level => 'emerg', message => "I've fallen and I can't get up\n" );
DESCRIPTION
This class provides a null logging object. Messages can be sent to the object but it does nothing with them.METHODS
- * new(%p)
- This method takes a hash of parameters. The following options are valid:
-
- * name ($)
- The name of the object (not the filename!). Required.
- * min_level ($)
- The minimum logging level this object will accept. See the Log::Dispatch documentation on Log Levels for more information. Required.
- * max_level ($)
- The maximum logging level this obejct will accept. See the Log::Dispatch documentation on Log Levels 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).
- * 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" or "log_to" methods 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).
