NAME
       [TAP::Parser::ResultFactory](https://www.chedong.com/phpMan.php/perldoc/TAP%3A%3AParser%3A%3AResultFactory/markdown) - Factory for creating [TAP::Parser](https://www.chedong.com/phpMan.php/perldoc/TAP%3A%3AParser/markdown) output
       objects

SYNOPSIS
         use [TAP::Parser::ResultFactory](https://www.chedong.com/phpMan.php/perldoc/TAP%3A%3AParser%3A%3AResultFactory/markdown);
         my $token   = {...};
         my $factory = [TAP::Parser::ResultFactory](https://www.chedong.com/phpMan.php/perldoc/TAP%3A%3AParser%3A%3AResultFactory/markdown)->new;
         my $result  = $factory->make_result( $token );

VERSION
       Version 3.43

   DESCRIPTION
       This is a simple factory class which returns a [TAP::Parser::Result](https://www.chedong.com/phpMan.php/perldoc/TAP%3A%3AParser%3A%3AResult/markdown)
       subclass representing the current bit of test data from TAP (usually a
       single line).  It is used primarily by [TAP::Parser::Grammar](https://www.chedong.com/phpMan.php/perldoc/TAP%3A%3AParser%3A%3AGrammar/markdown).  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 $result = [TAP::Parser::ResultFactory](https://www.chedong.com/phpMan.php/perldoc/TAP%3A%3AParser%3A%3AResultFactory/markdown)->make_result($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](https://www.chedong.com/phpMan.php/perldoc/TAP%3A%3AParser%3A%3AResult/markdown)';

         # register with the factory:
         [TAP::Parser::ResultFactory](https://www.chedong.com/phpMan.php/perldoc/TAP%3A%3AParser%3A%3AResultFactory/markdown)->register_type( 'my_type' => __PACKAGE__ );

         # use it:
         my $r = [TAP::Parser::ResultFactory](https://www.chedong.com/phpMan.php/perldoc/TAP%3A%3AParser%3A%3AResultFactory/markdown)->( { type => 'my_type' } );

       Your custom type should then be picked up automatically by the
       [TAP::Parser](https://www.chedong.com/phpMan.php/perldoc/TAP%3A%3AParser/markdown).

SUBCLASSING
       Please see "SUBCLASSING" in [TAP::Parser](https://www.chedong.com/phpMan.php/perldoc/TAP%3A%3AParser/markdown) 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](https://www.chedong.com/phpMan.php/perldoc/TAP%3A%3AParser%3A%3AResult/markdown)->new" is never called, $tokens are reblessed.
           This will change in a future version!

       3.  [TAP::Parser::Result](https://www.chedong.com/phpMan.php/perldoc/TAP%3A%3AParser%3A%3AResult/markdown) subclasses will register themselves with
           [TAP::Parser::ResultFactory](https://www.chedong.com/phpMan.php/perldoc/TAP%3A%3AParser%3A%3AResultFactory/markdown) directly:

             package MyFooResult;
             [TAP::Parser::ResultFactory](https://www.chedong.com/phpMan.php/perldoc/TAP%3A%3AParser%3A%3AResultFactory/markdown)->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](https://www.chedong.com/phpMan.php/perldoc/TAP%3A%3AParser%3A%3AResultFactory/markdown)';

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

         1;
