DESCRIPTION

This class is a file logger class for use with Courier::Filter and its filter modules. It is derived from Courier::Filter::Logger::IOHandle.

Constructor

The following constructor is provided:

new(%options): RETURNS Courier::Filter::Logger::File; THROWS Courier::Error

Creates a new logger that logs messages as lines to a file. Opens the file for writing, creating it if necessary.

%options is a list of key/value pairs representing any of the following options:

file_name

REQUIRED. The name of the file to which log messages should be written.

timestamp

A boolean value controlling whether every log message line should be prefixed with a timestamp (in local time, in ISO format). Defaults to false.

Instance methods

The following instance methods are provided, as inherited from Courier::Filter::Logger::IOHandle:

log_error($text): THROWS Perl exceptions

Logs the error message given as $text (a string which may contain newlines). Prefixes each line with a timestamp if the timestamp option has been set through the constructor.

log_rejected_message($message, $reason): THROWS Perl exceptions

Logs the Courier::Message given as $message as having been rejected due to $reason (a string which may contain newlines).
