All Known Implementing Classes:

BaseTagger, DemoTagger
```
public interface Tagger
```
The part-of-speech tagger interface, whose implementations are usually language-dependent.

Method Summary

All Methods Instance Methods Abstract Methods
Modifier and Type	Method	Description
`AnalyzedTokenReadings`	`createNullToken(java.lang.String token, int startPos)`	Create the AnalyzedToken used for whitespace and other non-words.
`AnalyzedToken`	`createToken(java.lang.String token, java.lang.String posTag)`	Create a token specific to the language of the implementing class.
`java.util.List<AnalyzedTokenReadings>`	`tag(java.util.List<java.lang.String> sentenceTokens)`	Returns a list of `AnalyzedToken`s that assigns each term in the sentence some kind of part-of-speech information (not necessarily just one tag).

- Method Detail
  - tag
```
java.util.List<AnalyzedTokenReadings> tag(java.util.List<java.lang.String> sentenceTokens)
                                   throws java.io.IOException
```
    Returns a list of AnalyzedTokens that assigns each term in the sentence some kind of part-of-speech information (not necessarily just one tag).
    Note that this method takes exactly one sentence. Its implementation may implement special cases for the first word of a sentence, which is usually written with an uppercase letter.
    
    Parameters:
    
    sentenceTokens - the text as returned by a WordTokenizer
    
    Throws:
    
    java.io.IOException
  - createNullToken
```
AnalyzedTokenReadings createNullToken(java.lang.String token,
                                      int startPos)
```
    Create the AnalyzedToken used for whitespace and other non-words. Use null as the POS tag for this token.
  - createToken
```
AnalyzedToken createToken(java.lang.String token,
                          java.lang.String posTag)
```
    Create a token specific to the language of the implementing class.
