              int offset,
              int count)
```
    Return the most specific value stored for this byte sequence. If not found, returns null or a default values as specified by calling setDefaultValue(T).
  - addPath
```
public void addPath(T value,
                    byte[]... parts)
```
    Store the given value at the specified path.
  - setDefaultValue
```
public void setDefaultValue(T defaultValue)
```
    Sets the default value to use in find(byte[]) when no path matches.
  - getMaxDepth
```
public int getMaxDepth()
```
    Gets the maximum depth stored in this trie.
