It is used primarily by TAP::Parser::Grammar. Unless you're subclassing, you probably won't need to use this module directly. .SS "\s-1METHODS\s0" .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.

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. .SS "Example" .IX Subsection "Example" .Vb 1 \& package MyResultFactory; \& \& use strict; \& \& use MyResult; \& \& use base \*(AqTAP::Parser::ResultFactory\*(Aq; \& \& # force all results to be \*(AqMyResult\*(Aq \& sub class_for { \& return \*(AqMyResult\*(Aq; \& } \& \& 1; .Ve .SH "SEE ALSO" .IX Header "SEE ALSO" TAP::Parser, TAP::Parser::Result, TAP::Parser::Grammar
