  - build
```
public void build(byte[][] keys,
                  int[] values)
```
    构建
    
    参数:
    
    keys - 字节形式的键
    
    values - 值
  - build
```
public void build(List<String> keys,
                  int[] values)
```
  - open
```
public void open(InputStream stream)
          throws IOException
```
    Read from a stream. The stream must implement the available() method.
    
    参数:
    
    stream -
    
    抛出:
    
    IOException
  - save
```
public void save(OutputStream stream)
          throws IOException
```
    Saves the trie data into a stream.
    
    参数:
    
    stream -
    
    抛出:
    
    IOException
  - exactMatchSearch
```
public int exactMatchSearch(String key)
```
    Returns the corresponding value if the key is found. Otherwise returns -1. This method converts the key into UTF-8.
    
    参数:
    
    key - search key
    
    返回:
    
    found value
  - exactMatchSearch
```
public int exactMatchSearch(byte[] key)
```
    Returns the corresponding value if the key is found. Otherwise returns -1.
    
    参数:
    
    key - search key
    
    返回:
    
    found value
  - commonPrefixSearch
```
public List<Pair<Integer,Integer>> commonPrefixSearch(byte[] key,
                                                      int offset,
                                                      int maxResults)
```
    Returns the keys that begins with the given key and its corresponding values. The first of the returned pair represents the length of the found key.
    
    参数:
    
    key -
    
    offset -
    
    maxResults -
    
    返回:
    
    found keys and values
  - size
```
public int size()
```
    大小
    
    返回:
