our @ISA = qw/Metabase::Fact::String/;
sub content_metadata {

return {
'size' => [ '//num' => length $self->content ],
};
}

$self->SUPER::validate_content;

}

...and then...

  # using the fact class
  my $fact = MyFact->new(

    content  => "Hello World",
  );
  $client->send_fact($fact);

DESCRIPTION

Base class for facts that are just strings of text. Strings must be characters, not bytes.

You may wish to implement a "content_metadata" method to generate metadata about the hash contents.

You should also implement a "validate_content" method to validate the structure of the hash you're given.
