Usage
# create a new tree
rtree = ::FFI::RadixTree::Tree.new
# add key/value pairs to the tree
rtree.push("key1", "value1")
rtree.push("key2", ["value2", "value3"])
rtree.push("key3", { :attr1 => "value4", :attr2 => "value5" })
# work with the collection
if rtree.has_key?("key1")
val = rtree.get("key2")
rtree.set("key3", "value6")
end
# search the tree using the keys
# keys based off the root word: "manage"
rtree.push("manage", "base verb")
rtree.push("managed", "past tense")
rtree.push("manager", "noun")
rtree.push("managers", "plural noun")
rtree.push("managing", "present tense")
# Find the key that matches the _most_ of the beggining of the search term
rtree.longest_prefix("managerial") # returns "manager"
rtree.longest_prefix_and_value("managerial") # returns ["manager", "noun"]
rtree.longest_prefix_value("managerial") # returns "noun"
# Find all values whose keys match the _most_ of the beginning of the search term
rtree.greedy_match("managerial") # returns ["noun", "plural noun"]
# Find all values whose keys are included _anywhere_ in the search term
rtree.greedy_substring_match("I managed to jump") # returns ["base verb", "past tense"]Development
