Interface Tokenizer

All Known Implementing Classes:

DefaultStreamTokenizer, DefaultTokenizer, PosUimaTokenizer, UimaTokenizer

public interface Tokenizer

A representation of a tokenizer. Different applications may require different kind of tokenization (say rules based vs more formal NLP approaches)

Method Summary

Modifier and Type	Method and Description
int	countTokens() The number of tokens in the tokenizer
java.util.List<java.lang.String>	getTokens() Returns a list of all the tokens
boolean	hasMoreTokens() An iterator for tracking whether more tokens are left in the iterator not
java.lang.String	nextToken() The next token (word usually) in the string
void	setTokenPreProcessor(TokenPreProcess tokenPreProcessor) Set the token pre process
