NAME
Bio::Phenotype::MeSH::Twig - Context for a MeSH term
SYNOPSIS
use Bio::Phenotype::MeSH::Twig
# create a twig object
my $twig = Bio::Phenotype::MeSH::Twig->new();
# the term has only one parent in any twig
$twig->parent('Fats');
# a twig makeas sense only in the context of a term
# which is a Bio::Phenotype::MeSH::Term object
# a term can have many twigs i.e. it can appear in many places in
# the hierarchy
#
$ term->add_twig($twig);
# adding the twig into a term adds a link into into it
$twig->term eq $term;
# a twig can know about other terms under the parant node
$twig->add_sister('Bread', 'Candy', 'Cereals');
print join ( ', ', $twig->each_sister()), "
";
# a twig can know about other terms under this term
$twig->add_child('Butter', 'Margarine');
print join ( ', ', $twig->each_child()), "
";
DESCRIPTION
This class represents the immediate surrounding of a MeSH term. It keeps track on nodes names above the current node ('parent') other nodes
at the same level ('sisters') and nodes under it ('children'). Note that these are name strings, not objects.
Each twig can be associated with only one term, but term can have multiple twigs. (Twigs can be though to be roles for a term.)
