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 $p{message} } DESCRIPTION
This module should be used as a base class to implement Log::Dispatch::* objects that send their log messages via email. Implementing a subclass simply requires the code shown in the SYNOPSIS with a real implementation of the "send_email()" method. CONSTRUCTOR
The constructor takes the following parameters in addition to the standard parameters documented in Log::Dispatch::Output: o subject ($) The subject of the email messages which are sent. Defaults to "$0: log email" o to ($ or @) Either a string or a list reference of strings containing email addresses. Required. o from ($) A string containing an email address. This is optional and may not work with all mail sending methods. o 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. METHODS
o send_email(%p) This is the method that must be subclassed. For now the only parameter in the hash is 'message'. o flush If the object is buffered, then this method will call the "send_email()" method to send the contents of the buffer and then clear the buffer. o DESTROY On destruction, the object will call "flush()" to send any pending email.

NAME
Log::Dispatch::Output - Base class for all Log::Dispatch::* objects SYNOPSIS
package Log::Dispatch::MySubclass; use Log::Dispatch::Output; use base qw( Log::Dispatch::Output ); sub new { my $proto = shift; my $class = ref $proto || $proto; my %p = @_; my $self = bless {}, $class; $self->_basic_init(%p); # Do more if you like return $self; } sub log_message { my $self = shift; my %p = @_; # Do something with message in $p{message} } 1; DESCRIPTION
This module is the base class from which all Log::Dispatch::* objects should be derived. CONSTRUCTOR
The constructor, "new", must be overridden in a subclass. See Output Classes for a description of the common parameters accepted by this constructor. METHODS
o _basic_init(%p) This should be called from a subclass's constructor. Make sure to pass the arguments in @_ to it. It sets the object's name and minimum level. It also sets up two other attributes which are used by other Log::Dispatch::Output methods, level_names and level_numbers. o name Returns the object's name. o min_level Returns the object's minimum log level. o max_level Returns the object's maximum log level. o accepted_levels Returns a list of the object's accepted levels (by name) from minimum to maximum. o log( level => $, message => $ ) Sends a message if the level is greater than or equal to the object's minimum level. This method applies any message formatting callbacks that the object may have. o _should_log ($) This method is called from the "log()" method with the log level of the message to be logged as an argument. It returns a boolean value indicating whether or not the message should be logged by this particular object. The "log()" method will not process the message if the return value is false. o _level_as_number ($) This method will take a log level as a string (or a number) and return the number of that log level. If not given an argument, it returns the calling object's log level instead. If it cannot determine the level then it will croak. o add_callback( $code ) Adds a callback (like those given during construction). It is added to the end of the list of callbacks. Subclassing This class should be used as the base class for all logging objects you create that you would like to work under the Log::Dispatch architecture. Subclassing is fairly trivial. For most subclasses, if you simply copy the code in the SYNOPSIS and then put some functionality into the "log_message" method then you should be all set. Please make sure to use the "_basic_init" method as directed. The actual logging implementation should be done in a "log_message" method that you write. Do not override "log"!. AUTHOR
