NAME

Log::Dispatch::File - Object that accepts messages and does nothing

SYNOPSIS

  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).
