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 3.48

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;
