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.
