NAME

Exception::Class::Try::Catch - Try::Catch for Exception::Class

SYNOPSIS

use Exception::Class::Try::Catch;

try {
    My::Exception::Class->throw('my error');
} catch {
    if ($_->isa('Specific::Exception')) {
        handle_specific_exception($_);
    } elsif ($_->isa('Local::Exception')) {
        handle_local_exception($_);
    } else {
        # $_ is always object of 'Exception::Class::Base'
        handle_base_exception($_);
    }
};

try {
    die 'my error';
} catch {
    # $_ is always object of 'Exception::Class::Base'
    handle_base_exception($_);
    process_text_of_exception($_->error);
};

try {
    die 'my error';
} catch {
    $_->rethrow();
};

DESCRIPTION

Exception::Class::Try::Catch provides try/catch syntactic sugar from Try::Catch for Exception::Class object exceptions.

In other words, the exception thrown in the try block will always be an object of the Exception::Class::Base class or its ancestor in the catch block. If you throw an exception of a different class, or just die with an error message, the exception will be stringified (by the as_string method, if available) and blessed into Exception::Class::Base. Exceptions inheriting from Exception::Class::Base remain unchanged.
