NAME ^

Bio::Tree::AnnotatableNode - A Tree Node with support for annotation

SYNOPSIS ^

    use Bio::Tree::AnnotatableNode;
    my $nodeA = Bio::Tree::AnnotatableNode->new();
    my $nodeL = Bio::Tree::AnnotatableNode->new();
    my $nodeR = Bio::Tree::AnnotatableNode->new();

    my $node = Bio::Tree::AnnotatableNode->new();
    $node->add_Descendents($nodeL);
    $node->add_Descendents($nodeR);

    print "node is not a leaf \n" if( $node->is_leaf);

    # $node is-a Bio::AnnotatableI, hence:
    my $ann_coll = $node->annotation();
    # $ann_coll is-a Bio::AnnotationCollectionI, hence:
    my @all_anns = $ann_coll->get_Annotations();
    # do something with the annotation objects

DESCRIPTION ^

Makes a Tree Node with Annotations, suitable for building a Tree. See Bio::Tree::Node for a full list of functionality.

FEEDBACK ^
