# Try::Tiny::ByClass(3pm)

selectively catch exceptions by class name

## 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
