NAME
TAP::Parser::ResultFactory - Factory for creating TAP::Parser output objects
SYNOPSIS
my
$token
= {...};
my
$factory
= TAP::Parser::ResultFactory->new;
my
$result
=
$factory
->make_result(
$token
);
VERSION
Version 3.17_02
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:
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
:
The factory itself is never instantiated (this may change in the future). This means that
_initialize
is never called.TAP::Parser::Result->new
is never called, $tokens are reblessed. This will change in a future version!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;
@ISA
=
qw( TAP::Parser::ResultFactory )
;
# force all results to be 'MyResult'
sub
class_for {
return
'MyResult'
;
}
