NAME
       Mail::SPF::Record - Abstract base class for SPF records

SYNOPSIS
   Creating a record from a string
           use Mail::SPF::v1::Record;

           my $record = Mail::SPF::v1::Record->new_from_string("v=spf1 a mx -all");

   Creating a record synthetically
           use Mail::SPF::v2::Record;

           my $record = Mail::SPF::v2::Record->new(
               scopes      => ['mfrom', 'pra'],
               terms       => [
                   Mail::SPF::Mech::A->new(),
                   Mail::SPF::Mech::MX->new(),
                   Mail::SPF::Mech::All->new(qualifier => '-')
               ],
               global_mods => [
                   Mail::SPF::Mod::Exp->new(domain_spec => 'spf-exp.example.com')
               ]
           );

DESCRIPTION
       Mail::SPF::Record is an abstract base class for SPF records.  It cannot be instantiated
       directly.  Create an instance of a concrete sub-class instead.

   Constructor
       The following constructors are provided:

       new(%options): returns Mail::SPF::Record
           Creates a new SPF record object.

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

           text
               A string denoting the unparsed text of the record.

           scopes
               A reference to an array of strings denoting the scopes that are covered by the
               record (see the description of the "scope" option of Mail::SPF::Request's "new"
               constructor).

           terms
               A reference to an array of Mail::SPF::Term (i.e. Mail::SPF::Mech or
               Mail::SPF::Mod) objects that make up the record.  Mail::SPF::GlobalMod objects
               must not be included here, but should be specified using the "global_mods" option
               instead.

           global_mods
               A reference to an array of Mail::SPF::GlobalMod objects that are global modifiers
               of the record.

       new_from_string($text, %options): returns Mail::SPF::Record; throws
       Mail::SPF::ENothingToParse, Mail::SPF::EInvalidRecordVersion, Mail::SPF::ESyntaxError
           Creates a new SPF record object by parsing the string and any options given.

   Class methods
       The following class methods are provided:

       version_tag_pattern: returns Regexp
           Abstract.  Returns a regular expression that matches a legal version tag.

           This method is abstract and must be implemented by sub-classes of Mail::SPF::Record.

       default_qualifier: returns string
           Returns the default qualifier, i.e. '+'.

       results_by_qualifier: returns hash of string
           Returns a reference to a hash that maps qualifiers to result codes as follows:

                Qualifier | Result code
               -----------+-------------
                    +     | pass
                    -     | fail
                    ~     | softfail
                    ?     | neutral

   Instance methods
       The following instance methods are provided:

       text: returns string; throws Mail::SPF::ENoUnparsedText
           Returns the unparsed text of the record.  Throws a Mail::SPF::ENoUnparsedText
           exception if the record was created synthetically instead of being parsed, and no text
           was provided.

       version_tag: returns string
           Abstract.  Returns the version tag of the record.

           This method is abstract and must be implemented by sub-classes of Mail::SPF::Record.

       scopes: returns list of string
           Returns a list of the scopes that are covered by the record.  See the description of
           the "new" constructor's "scopes" option.

       terms: returns list of Mail::SPF::Term
           Returns a list of the terms that make up the record, excluding any global modifiers,
           which are returned by the "global_mods" method.  See the description of the "new"
           constructor's "terms" option.

       global_mods: returns list of Mail::SPF::GlobalMod
           Returns a list of the global modifiers of the record, ordered ascending by modifier
           precedence.  See the description of the "new" constructor's "global_mods" option.

       global_mod($mod_name): returns Mail::SPF::GlobalMod
           Returns the global modifier of the given name if it is present in the record.  Returns
           undef otherwise.  Use this method if you wish to retrieve a specific global modifier
           as opposed to getting all of them.

       stringify: returns string
           Returns the record's version tag and terms (including the global modifiers) formatted
           as a string.  You can simply use a Mail::SPF::Record object as a string for the same
           effect, see "OVERLOADING".

       eval($server, $request): throws Mail::SPF::Result
           Evaluates the SPF record in the context of the request parameters represented by the
           given Mail::SPF::Request object.  The given Mail::SPF::Server object is used for
           performing DNS look-ups.  Throws a Mail::SPF::Result object matching the outcome of
           the evaluation; see Mail::SPF::Result.  See RFC 4408, 4.6 and 4.7, for the exact
           algorithm used.

OVERLOADING
       If a Mail::SPF::Record object is used as a string, the "stringify" method is used to
       convert the object into a string.
