NAME

Log::Dispatch::Email - Base class for objects that send log messages via email

SYNOPSIS

  package Log::Dispatch::Email::MySender


  use Log::Dispatch::Email;
  use base qw( Log::Dispatch::Email );


  sub send_email
  {
      my $self = shift;
      my %p = @_;


      # Send email somehow.  Message is in $p{message}
  }

DESCRIPTION

This module should be used as a base class to implement Log::Dispatch::* objects that send their log messages via email. Implementing a subclass simply requires the code shown in the SYNOPSIS with a real implementation of the CWsend_email() method.

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 for more information. Required.
* max_level ($)
The maximum logging level this obejct will accept. See the Log::Dispatch documentation for more information. This is not required. By default the maximum is the highest possible level (which means functionally that the object has no maximum).
* subject ($)
The subject of the email messages which are sent. Defaults to $0: log email
* to ($ or \@)
Either a string or a list reference of strings containing email addresses. Required.
* from ($)
A string containing an email address. This is optional and may not work with all mail sending methods.
* buffered (0 or 1)
This determines whether the object sends one email per message it is given or whether it stores them up and sends them all at once. The default is to buffer messages.
* 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 CWlog or CWlog_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 CWlog() method (in Log::Dispatch::Output).
* send_email(%p)
This is the method that must be subclassed. For now the only parameter in the hash is 'message'.
* flush
If the object is buffered, then this method will call the CWsend_email() method to send the contents of the buffer and then clear the buffer.
* DESTROY
On destruction, the object will call CWflush() to send any pending email.
