NAME

MooseX::Constructor::AllErrors::Error::Misc - represents a miscellaneous error

VERSION

version 0.025

DESCRIPTION

This class represents an error occurring at construction time that cannot be classified as one of the other error types. The error message is an arbitrary string, which describes the nature of the error.

Its creation is a little different than the other error types - it must be explicitly created by the generating class, usually in either BUILDARGS or BUILD:

sub BUILD
{
    my ($self, $args) = @_;

    my @errors;

    # either name *or* id is required
    push @errors, MooseX::Constructor::AllErrors::Error::Misc->new(
        message => 'Either \'name\' or \'id\' must be provided',
    ) if not defined $args->{name} and not defined $args->{id};

    ...;

    if (@errors)
    {
        my $error = MooseX::Constructor::AllErrors::Error::Constructor->new(
            caller => [ caller( Class::MOP::class_of($self)->is_immutable ? 2 : 4) ],
        );
        $error->add_error($_) foreach @errors;
        die $error;
    }
}

This code is a little long and unwieldy; it is likely that a shortcut will soon be added; it has been suggested that support for a VALIDATE sub be added, which is automatically called at construction time before BUILD, to perform validations with no side effect. Stay tuned to upcoming releases!
