![]() The pointers in the node are placed between the ordered keys so that there is one pointer on either end and one pointer in between each value. STRUCTUREĮach node in a B+ tree contains n pointers and n - 1 keys. This implementation supports B+ trees using an arbitrary n value. They are similar to 2-3-4 Trees and Red-Black Trees. They are useful for indexing large bodies of data. While (my ($key, $value) = $tree->each) ) ī+ trees are balanced trees which provide an ordered map from keys to values. # Iterate through each key/value pair just like built-in each operator # We don't like the word 'WAY ', so let's remove it My $string = "THERE'S MORE THAN ONE WAY TO DO IT" # TMTOWTDI # These arguments are actually the defaults Tree::BPTree - Perl implementation of B+ trees SYNOPSIS use Tree::BPTree
