NAME
Data::LetterTree - Native letter tree Perl bindingSYNOPSIS
use Data::LetterTree; my $tree = Data::LetterTree->new(); $tree->add_data('foo', 'stuff'); $tree->add_data('bar', 'more'); $tree->add_data('bar', 'stuff'); foreach my $word (qw/foo bar baz/) { if ($tree->has_word($word)) { print "$word:" . $tree->get_data($word) . "\n"; } else { print "$word: not found\n"; }
DESCRIPTION
This module provides perl binding over a native implementation of a letter tree, allowing to index any kind of perl scalar variable by a large set of string with a reduced memory footprint over native perl hashes by sharing their prefixes.METHODS
new()
Creates and returns a new "Data::LetterTree" object.
$tree->add_data($word, $data)
$tree->add_data($word, $data)
Add $word in the tree, pushing $data in indexed values.
$tree->has_word($word)
$tree->has_word($word)
Return a true value if $word is present in the tree.
$tree->get_data($word)
$tree->get_data($word)
Return all values indexed by $word as a list.
