.SH "NAME"
TAP::Parser::ResultFactory \- Factory for creating TAP::Parser output objects
.SH "SYNOPSIS"
.IX Header "SYNOPSIS"
.Vb 4
\&  use TAP::Parser::ResultFactory;
\&  my $token   = {...};
\&  my $factory = TAP::Parser::ResultFactory\->new;
\&  my $result  = $factory\->make_result( $token );
.Ve
.SH "VERSION"
.IX Header "VERSION"
Version 3.36
.SS "\s-1DESCRIPTION\s0"
.IX Subsection "DESCRIPTION"
This is a simple factory class which returns a TAP::Parser::Result subclass
representing the current bit of test data from \s-1TAP \s0(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.

.IX Subsection "METHODS"
.SS "Class Methods"
.IX Subsection "Class Methods"
\fI\f(CI\*(C`new\*(C'\fI\fR
.IX Subsection "new"
.PP
Creates a new factory class.
\&\fINote:\fR You currently don't need to instantiate a factory in order to use it.
.PP
\fI\f(CI\*(C`make_result\*(C'\fI\fR
.IX Subsection "make_result"
.PP
Returns an instance the appropriate class for the test token passed in.
.PP
.Vb 1
\&  my $result = TAP::Parser::ResultFactory\->make_result($token);
.Ve
.PP
Can also be called as an instance method.
.PP
\fI\f(CI\*(C`class_for\*(C'\fI\fR
.IX Subsection "class_for"
.PP
Takes one argument: \f(CW$type\fR.  Returns the class for this \f(CW$type\fR, or \f(CW\*(C`croak\*(C'\fRs
with an error.
.PP
\fI\f(CI\*(C`register_type\*(C'\fI\fR
.IX Subsection "register_type"
.PP
Takes two arguments: \f(CW$type\fR, \f(CW$class\fR
.PP
This lets you override an existing type with your own custom type, or register
a completely new type, eg:
.PP
.Vb 4
\&  # create a custom result type:
\&  package MyResult;
\&  use strict;
\&  use base \*(AqTAP::Parser::Result\*(Aq;
\&
\&  # register with the factory:
\&  TAP::Parser::ResultFactory\->register_type( \*(Aqmy_type\*(Aq => _\|_PACKAGE_\|_ );
\&
\&  # use it:
\&  my $r = TAP::Parser::ResultFactory\->( { type => \*(Aqmy_type\*(Aq } );
.Ve
.PP
Your custom type should then be picked up automatically by the TAP::Parser.
.SH "SUBCLASSING"
.IX Header "SUBCLASSING"
Please see \*(L"\s-1SUBCLASSING\*(R"\s0 in TAP::Parser for a subclassing overview.
.PP
There are a few things to bear in mind when creating your own
\&\f(CW\*(C`ResultFactory\*(C'\fR:
.IP "1." 4
The factory itself is never instantiated (this \fImay\fR change in the future).
This means that \f(CW\*(C`_initialize\*(C'\fR is never called.
.IP "2." 4
\&\f(CW\*(C`TAP::Parser::Result\->new\*(C'\fR is never called, \f(CW$tokens\fR are reblessed.
This \fIwill\fR change in a future version!
.IP "3." 4
TAP::Parser::Result subclasses will register themselves with
TAP::Parser::ResultFactory directly:
.Sp
.Vb 2
\&  package MyFooResult;
\&  TAP::Parser::ResultFactory\->register_type( foo => _\|_PACKAGE_\|_ );
.Ve
.Sp
Of course, it's up to you to decide whether or not to ignore them.

\&  use MyResult;
