- Method Detail
  - builder
```
static <V> Trie.Builder<V> builder()
```
    Start building a trie.
  - getOrNull
```
@Nullable
default V getOrNull(CharSequence str)
```
    Returns the value associated with the longest matched prefix, or null if there wasn't a match. For example: for a trie containing an ("abc", 10) entry trie.getOrNull("abcd") will return 10.
  - getOrDefault
```
V getOrDefault(CharSequence str,
               V defaultValue)
```
    Returns the value associated with the longest matched prefix, or the defaultValue if there wasn't a match. For example: for a trie containing an ("abc", 10) entry trie.getOrDefault("abcd", -1) will return 10.
  - contains
```
default boolean contains(CharSequence str)
```
    Returns true if this trie contains the prefix str.
