This module implements a memory-efficient node type (for trees, skip lists
|
|
and similar data structures) for Perl.
|
|
|
|
You may ask "Why bother implementing an ordered structure such as a tree
|
|
when Perl has hashes built-in?" Since Perl is optimized for speed over
|
|
memory usage, hashes (and lists) use a lot of memory.
|
|
|
|
So the purpose of this package is to provide a simple low-level Node class
|
|
which can be used as a base class to implement various kinds of tree
|
|
structures. Each node has a key/value pair and a variable number of
|
|
"children" pointers.
|
|
|
|
How nodes are organized or the algorithm used to organize them is for you
|
|
to implement.
|
|
|
|
There is no Pure-perl version because this package was written to overcome
|
|
limitations of Perl.
