Bio::Phylo::Unparsers::Adjacency - Serializer used by Bio::Phylo::IO, no serviceable parts inside
This module turns a tree structure into tabular data organized as an adjacency
list, i.e. child -> parent relationships. The table at least has the
following columns: child and parent. length is interpreted as branch
length. Columns starting with node: are created for semantic annotations
to the focal node, columns starting with branch: are created for the focal
branch. Records are listed in pre-order, so that references to parent
nodes can be resolved immediately. Consequently, the root is the first record,
without a parent. Example:
Becomes (with an extra example annotation):
child parent length node:dcterms:identifier
n2 0 35462
n1 n2 3 34987
A n1 1 73843
B n1 2 98743
C n2 4 39847
