NAME

Try::Tiny::ByClass - selectively catch exceptions by class name

SYNOPSIS

  use Try::Tiny::ByClass;
  
  try {
        die $exception_object;
  } catch_case [
    'Some::Class' => sub {
      # handle Some::Class exceptions
    },
    'Exception::DivByZero' => sub {
      # handle Exception::DivByZero exceptions
    },
  ], finally {
    # always do this
  };

DESCRIPTION

This module is a simple wrapper around "Try::Tiny", which see. It re-exports "try", "catch", and "finally".

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.

Functions

Intended to be used instead of "catch" in the second argument position of "try".

Instead of a block it takes a reference to an array of "CLASS => CODEREF" pairs, which it passes on to "dispatch" in "Dispatch::Class".

SEE ALSO

Try::Tiny, Dispatch::Class
