Radix

<a href="http://goci.me/project/github.com/sauerbraten/radix"> <img src="http://goci.me/project/image/github.com/sauerbraten/radix" /> </a>

An implementation of a radix tree in Go. See

Donald R. Morrison. "PATRICIA -- practical algorithm to retrieve
information coded in alphanumeric". Journal of the ACM, 15(4):514-534,
October 1968

Or the wikipedia article.

Usage

Get the package:

$ go get github.com/sauerbraten/radix

Import the package:

import (
	"github.com/sauerbraten/radix"
)

You can use the tree as a key-value structure, where every node's value can have a different type:

r := radix.New()
r.Set("one", "1")
r.Set("twoAndThree", []int{2, 3})
fmt.Printf("%v, %v, %v\n", r.Get("one"), r.Get("twoAndThree").([]int)[0], r.Get("twoAndThree").([]int)[1])

// prints 1, 2, 3

Or you can of course just use it to look up strings, like so:

r := radix.New()
r.Set("foo", true)
fmt.Printf("foo is contained: %v\n", r.Get("foo"))
