NAME

Error::Hierarchy - support for hierarchical exception classes

SYNOPSIS

package Error::Hierarchy::ReadOnlyAttribute;

use warnings;
use strict;

use base 'Error::Hierarchy';

Error::Hierarchy::ReadOnlyAttribute->mk_accessors(qw(attribute));

use constant default_message => '[%s] is a read only attribute';

use constant PROPERTIES => ( 'attribute' );

Meanwhile...

package main;

use Error::Hierarchy::Mixin;

if (...) {
    Error::Hierarchy::ReadOnlyAttribute->
        throw(attribute => 'foo');
}

DESCRIPTION

This class provides support for hierarchical exception classes. It builds upon Error and is thus compatible with its try/catch mechanism. However, it records a lot more information such as the package, filename and line where the exception occurred, a complete stack trace, the hostname and a uuid.

It provides a stringification that is extensible with any properties your own exceptions might define.

FIXME: This documentation is still only a stub - I still need to describe all the goodies this class provides. For now, see the synopsis and the other classes in this distribution.
