It re-exports \f(CW\*(C`try\*(C'\fR, \f(CW\*(C`catch\*(C'\fR, and \&\f(CW\*(C`finally\*(C'\fR. .PP In addition, it provides a way to catch only some exceptions by filtering on the class (including superclasses and consumed roles) of an exception object. .SS Functions .IX Subsection "Functions" .IP "catch_case ($;@)" 4 .IX Item "catch_case ($;@)" Intended to be used instead of \f(CW\*(C`catch\*(C'\fR in the second argument position of \f(CW\*(C`try\*(C'\fR. .Sp Instead of a block it takes a reference to an array of \f(CW\*(C`CLASS => CODEREF\*(C'\fR pairs, which it passes on to \f(CW\*(C`dispatch\*(C'\fR in \&\f(CW\*(C`Dispatch::Class\*(C'\fR. .SH "SEE ALSO" .IX Header "SEE ALSO" Try::Tiny, Dispatch::Class .SH AUTHOR .IX Header "AUTHOR" Lukas Mai, \f(CW\*(C`\*(C'\fR .SH "COPYRIGHT & LICENSE" .IX Header "COPYRIGHT & LICENSE" Copyright 2013 Lukas Mai. .PP This program is free software; you can redistribute it and/or modify it under the terms of either: the GNU General Public License as published by the Free Software Foundation; or the Artistic License. .PP See http://dev.perl.org/licenses/ for more information.
