NAME

    Mail::Colander - Categorize and manage email messages

VERSION

    This document describes Mail::Colander version 0.004.

SYNOPSIS

       use Mail::Colander;
    
       my $sieve = Mail::Colander->new(annotator => \%data_annotation_def);
    
       # 
       my $policy = $sieve->policy_for(foo => $element);
       if ($policy eq 'delete') { ... }

DESCRIPTION

    This is a wrapper around Data::Annotation thought for dealing with
    email messages. This very class only contains an annotator member,
    which is supposed to be a Data::Annotation instance, and wraps the call
    to "Data::Annotation::evaluate" inside a more expressive "policy_for"
    method.

INTERFACE

 Constructor

       my $ms = Mail::Colander->new(annotator => \%definition);   # OR
    
       my $da = Data::Annotation->new(%definition);
       my $ms = Mail::Colander->new(annotator => $da);

    Get a new instance, with the underlying Data::Annotation object either
    passed directly, or passed through a definition hash reference that can
    then be turned into a Data::Annotation object.

 Accessors

  annotator

       my $data_annotation_instance = $ms->annotator;

    Get the underlying Data::Annotation object.

 Methods

  description

       my $text = $ms->description;

    Same as $ms->annotator->description.

  has_chain_for

       my $text = $ms->has_chain_for($chain_name);

    Same as $ms->annotator->has_chain_for($chain_name).

  policy_for

       my $policy = $ms->policy_for($chain, $element);

    Determine the annotations for $element, starting at $chain. See
    Data::Annotation for the details.

    Depending on the definition, a policy will then tell what to do next,
    e.g. in a SMTP server context the policies might be returned as accept
    or reject and then the server would act accordingly.

BUGS AND LIMITATIONS

    Minimul perl version 5.24.
