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

catch_case ($;@)

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
