NAME
       TAP::Parser::ResultFactory - Factory for creating TAP::Parser output objects

SYNOPSIS
         use TAP::Parser::ResultFactory;
         my $token   = {...};
         my $factory = TAP::Parser::ResultFactory->new;
         my $result  = $factory->make_result( $token );

VERSION
       Version 3.42

   DESCRIPTION
       This is a simple factory class which returns a TAP::Parser::Result subclass representing
       the current bit of test data from TAP (usually a single line).  It is used primarily by
       TAP::Parser::Grammar.  Unless you're subclassing, you probably won't need to use this
       module directly.

   METHODS
   Class Methods
       "new"

       Creates a new factory class.  Note: You currently don't need to instantiate a factory in
       order to use it.

       "make_result"

       Returns an instance the appropriate class for the test token passed in.

         my $result = TAP::Parser::ResultFactory->make_result($token);

       Can also be called as an instance method.

       "class_for"

       Takes one argument: $type.  Returns the class for this $type, or "croak"s with an error.

       "register_type"

       Takes two arguments: $type, $class

       This lets you override an existing type with your own custom type, or register a
       completely new type, eg:

         # create a custom result type:
         package MyResult;
         use strict;
         use base 'TAP::Parser::Result';

         # register with the factory:
         TAP::Parser::ResultFactory->register_type( 'my_type' => __PACKAGE__ );

         # use it:
         my $r = TAP::Parser::ResultFactory->( { type => 'my_type' } );

       Your custom type should then be picked up automatically by the TAP::Parser.

SUBCLASSING
       Please see "SUBCLASSING" in TAP::Parser for a subclassing overview.

       There are a few things to bear in mind when creating your own "ResultFactory":

       1.  The factory itself is never instantiated (this may change in the future).  This means
           that "_initialize" is never called.

       2.  "TAP::Parser::Result->new" is never called, $tokens are reblessed.  This will change
           in a future version!

       3.  TAP::Parser::Result subclasses will register themselves with
           TAP::Parser::ResultFactory directly:

             package MyFooResult;
             TAP::Parser::ResultFactory->register_type( foo => __PACKAGE__ );

           Of course, it's up to you to decide whether or not to ignore them.

   Example
         package MyResultFactory;

         use strict;

         use MyResult;

         use base 'TAP::Parser::ResultFactory';

         # force all results to be 'MyResult'
         sub class_for {
           return 'MyResult';
         }

         1;
