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;
