=head1 SYNOPSIS

 package My::Class;
 use base qw( SWISH::Prog::Class );

 # see METHODS for what you get for free

=head1 DESCRIPTION

SWISH::Prog::Class is a subclass of Rose::ObjectX::CAF.
It's a base class useful for making simple accessor/mutator methods.
SWISH::Prog::Class implements some additional methods and features
useful for SWISH::Prog projects.

=head1 METHODS

=head2 new( I<params> )

Constructor. Returns a new object. May take a hash or hashref
as I<params>.

=head2 init

Override init() in your subclass to perform object maintenance at
construction time. Called by new().

=head2 debug

Get/set the debug level. Default is 0.

=head2 warnings

Get/set the warnings level. Default is 0.

=head2 verbose

Get/set flags affecting the verbosity of the program.

=cut

sub init {
    my $self = shift;
    $self->SUPER::init(@_);
    $self->{debug}   ||= $ENV{PERL_DEBUG}   || 0;
    $self->{verbose} ||= $ENV{PERL_VERBOSE} || 0;
    $self->{_start} = time();
    return $self;
}

=head2 elapsed

Returns the elapsed time in seconds since object was created.

=cut

sub elapsed {
    return time() - shift->{_start};
}

=head2 dump( [I<data>] )

Returns $self (and I<data> if present) via Data::Dump::dump. Useful for peering
inside an object or other scalar.

=cut

=head2 verify_isa_swish_prog_config([I<config>])

Returns a SWISH::Prog::Config object based on I<config>. 

I<config> may be a readable file name or a SWISH::Prog::Config object.

Will croak if I<config> is neither of the above.

=cut

sub verify_isa_swish_prog_config {
    my $self    = shift;
    my $config2 = shift;

    #carp "verify_isa_config: $config2";

    my $config2_object;
    if ( !$config2 ) {
        $config2_object = SWISH::Prog::Config->new();
    }
    elsif ( !blessed($config2) && -r $config2 ) {
        $config2_object = SWISH::Prog::Config->new($config2);
    }
    elsif ( !blessed($config2) && ref $config2 eq 'HASH' ) {
        $config2_object = SWISH::Prog::Config->new($config2);
    }
    elsif ( blessed($config2) ) {
        if ( !$config2->isa('SWISH::Prog::Config') ) {
            croak
                "config object does not inherit from SWISH::Prog::Config: $config2";
        }
        else {
            $config2_object = $config2;
        }
    }
    else {
        croak "$config2 is neither an object nor a readable file";
    }

    return $config2_object;
}
