critbitgo
|
|
=========
|
|
|
|
[Crit-bit trees](http://cr.yp.to/critbit.html) in golang and its applications.
|
|
|
|
This implementation extended to handle the key that contains a null character from [C implementation](https://github.com/agl/critbit).
|
|
|
|
Usage
|
|
--------
|
|
|
|
```go
|
|
// Create Trie
|
|
trie := critbitgo.NewTrie()
|
|
|
|
// Insert
|
|
trie.Insert([]byte("aa"), "value1")
|
|
trie.Insert([]byte("bb"), "value2")
|
|
trie.Insert([]byte("ab"), "value3")
|
|
|
|
// Get
|
|
v, ok := trie.Get([]byte("aa"))
|
|
fmt.Println(v, ok) // -> value1 true
|
|
|
|
// Iterate containing keys
|
|
trie.Allprefixed([]byte{}, func(key []byte, value interface{}) bool {
|
|
fmt.Println(key, value) // -> [97 97] value1
|
|
// [97 98] value3
|
|
// [98 98] value2
|
|
return true
|
|
})
|
|
|
|
// Delete
|
|
v, ok = trie.Delete([]byte("aa"))
|
|
fmt.Println(v, ok) // -> value1 true
|
|
v, ok = trie.Delete([]byte("aa"))
|
|
fmt.Println(v, ok) // -> <nil> false
|
|
```
