Error::Hierarchy
support for hierarchical exception classes

Error::Hierarchy - support for hierarchical exception classes


NAME

Error::Hierarchy - support for hierarchical exception classes


SYNOPSIS


    package Error::Hierarchy::ReadOnlyAttribute;

    use warnings;

    use strict;

    use base 'Error::Hierarchy';

    __PACKAGE__->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.
