Tree::Simple is a fully object-oriented implementation of a simple
n-ary tree. It is built upon the concept of parent-child
relationships, so therefore every Tree::Simple object has both a
parent and a set of children (who themselves may have children, and so
on). Every Tree::Simple object also has siblings, as they are just the
children of their immediate parent.
.
It can be used to model hierarchal information such as a file-system,
the organizational structure of a company, an object inheritance
hierarchy, versioned files from a version control system or even an
abstract syntax tree for use in a parser. It makes no assumptions as
to your intended usage, but instead simply provides the structure and
means of accessing and traversing said structure.
.
This module uses exceptions and a minimal Design By Contract
style. All method arguments are required unless specified in the
documentation, if a required argument is not defined an exception will
usually be thrown. Many arguments are also required to be of a
specific type, for instance the $parent argument to the constructor
must be a Tree::Simple object or an object derived from Tree::Simple,
otherwise an exception is thrown.
