Object::FromData - Throw arrayrefs or hashrefs at this to get an object

=head1 SYNOPSIS

    use Object::FromData;

    my $object = Object::FromData->new(
        {   ref => {
                foo      => 'bar',
                this     => 'that',
                _private => 'no method will be created',
                colors   => [qw/red blue green/],
                numbers  => {
                    un    => 1,
                    deux  => 2,
                    trois => 3,
                },
            },
        }
    );

    say $object->is_hashref;     # 1
    say $object->is_arrayref;    # 0

    say $object->foo;            # bar
    say $object->this;           # that
    say $object->_private;       # BOOM! No such method

    say $object->numbers->is_hashref;     # 0
    say $object->numbers->is_arrayref;    # 1
    say $object->numbers->deux;           # 2

    my $colors = $object->colors;
    while ( $colors->has_more ) {
        say $colors->next;    # red, blue, green on successive lines
    }

=head2 C

    my $object = Object::FromData->new({ ref => $ref });

Takes a hashref. The key of C must be a hashref or arrayref. Returns an
object. The object represents a hash or an arrayref as created by
C or C.

The primary purpose of this module was to be able to take arbitrary JSON from
a client and create an object I could safely embed in another object.

=cut

sub new {
    my ( $class, $arg_for ) = @_;

    my $ref = $arg_for->{ref}
      or confess "no ref() supplied to Object::FromData::new";
    if ( 'ARRAY' eq ref $ref ) {
        return Object::FromData::Array->_new( { ref => $ref } );
    }
    elsif ( 'HASH' eq ref $ref ) {
        return Object::FromData::Hash->_new( { ref => $ref } );
    }
    else {
        croak(
            "Don't know how to convert '$ref' into an object. I only handle arrayrefs and hashrefs"
        );
    }
}

=head1 BUGS

Please report any bugs or feature requests to C, or through
the web interface at L.  I will be notified, and then you'll
automatically be notified of progress on your bug as I make changes.

We've tried to keep the methods minimal, but because we're inheriting from
C and C, the latter might
have keys which override the main keys. If that happens, call the methods as
class methods, passing in the object as an argument:

    my %hash = (
        keys => [qw/foo bar baz/],
    );
    my $object = Object::FromData->new({ ref => \%hash });

    my @keys = $hash->keys; # returns an Object::FromData::Array instance of foo, bar, and baz
    my @keys = Object::FromData::Hash->keys($hash); # returns 'keys'
