=head1 NAME

Bio::Chado::Schema::Result::Phylogeny::Phylonode

=head1 DESCRIPTION

This is the most pervasive
       element in the phylogeny module, cataloging the "phylonodes" of
       tree graphs. Edges are implied by the parent_phylonode_id
       reflexive closure. For all nodes in a nested set implementation the left and right index will be *between* the parents left and right indexes.

=head1 ACCESSORS

=head2 phylonode_id

  data_type: 'integer'
  is_auto_increment: 1
  is_nullable: 0
  sequence: 'phylonode_phylonode_id_seq'

=head2 phylotree_id

  data_type: 'integer'
  is_foreign_key: 1
  is_nullable: 0

=head2 parent_phylonode_id

  data_type: 'integer'
  is_foreign_key: 1
  is_nullable: 1

Root phylonode can have null parent_phylonode_id value.

=head2 left_idx

  data_type: 'integer'
  is_nullable: 0

=head2 right_idx

  data_type: 'integer'
  is_nullable: 0

=head2 type_id

  data_type: 'integer'
  is_foreign_key: 1
  is_nullable: 1

Type: e.g. root, interior, leaf.

=head2 feature_id

  data_type: 'integer'
  is_foreign_key: 1
  is_nullable: 1

Phylonodes can have optional features attached to them e.g. a protein or nucleotide sequence usually attached to a leaf of the phylotree for non-leaf nodes, the feature may be a feature that is an instance of SO:match; this feature is the alignment of all leaf features beneath it.

=head2 label

  data_type: 'varchar'
  is_nullable: 1
  size: 255

=head2 distance

  data_type: 'double precision'
  is_nullable: 1

=head1 NESTEDSET OPERATIONS

Phylonodes support L<DBIx::Class::Tree::NestedSet> operations for
working with this tree-structured data.  See
L<DBIx::Class::Tree::NestedSet> for details.

B<CAVEAT:> As of L<DBIx::Class::Tree::NestedSet> 0.07, an important caveat of
these operations is that they cannot be chained with other resultsets.
This shortcoming is being addressed at the level of L<DBIx::Class> and
L<DBIx::Class::Tree::NestedSet> modules.
