All Implemented Interfaces:

Closeable, AutoCloseable
```
public final class WhitespaceTokenizer
extends CharTokenizer
```
A tokenizer that divides text at whitespace characters as defined by Character.isWhitespace(int). Note: That definition explicitly excludes the non-breaking space. Adjacent sequences of non-Whitespace characters form tokens.

- Constructor Detail
  - WhitespaceTokenizer
```
public WhitespaceTokenizer()
```
    Construct a new WhitespaceTokenizer.
  - WhitespaceTokenizer
```
public WhitespaceTokenizer(AttributeFactory factory)
```
    Construct a new WhitespaceTokenizer using a given AttributeFactory.
    
    Parameters:
    
    factory - the attribute factory to use for this Tokenizer
  - WhitespaceTokenizer
```
public WhitespaceTokenizer(AttributeFactory factory,
                           int maxTokenLen)
```
    Construct a new WhitespaceTokenizer using a given AttributeFactory.
    
    Parameters:
    
    factory - the attribute factory to use for this Tokenizer
    
    maxTokenLen - maximum token length the tokenizer will emit. Must be greater than 0 and less than MAX_TOKEN_LENGTH_LIMIT (1024*1024)
    
    Throws:
    
    IllegalArgumentException - if maxTokenLen is invalid.
