Field Detail

### lst

    protected List lst

### iter

    protected Iterator iter

Constructor Detail

### SinkTokenizer

    public SinkTokenizer(List input)

### SinkTokenizer

    public SinkTokenizer()

### SinkTokenizer

    public SinkTokenizer(int initCap)

Method Detail

### getTokens

    public List getTokens()

  Get the tokens in the internal List.

  WARNING: Adding tokens to this list requires the `reset()` method to be called in order for them to be made available. Also, this Tokenizer does nothing to protect against `ConcurrentModificationException`s in the case of adds happening while `TokenStream.next(org.apache.lucene.analysis.Token)` is being called.

  Returns:
    A List of `Token`s

### next

    public Token next()
               throws IOException

  Returns the next token out of the list of cached tokens

  Overrides:
    `next` in class `TokenStream`
  Returns:
    The next `Token` in the Sink.
  Throws:
    `IOException`

### add

    public void add(Token t)

  Override this method to cache only certain tokens, or new tokens based on the old tokens.

  Parameters:
    `t` - The `Token` to add to the sink

### close

    public void close()
               throws IOException

  Description copied from class: `Tokenizer`
  By default, closes the input Reader.

  Overrides:
    `close` in class `Tokenizer`
  Throws:
    `IOException`

### reset

    public void reset()
               throws IOException

  Reset the internal data structures to the start at the front of the list of tokens. Should be called if tokens were added to the list after an invocation of `TokenStream.next(Token)`

  Overrides:
    `reset` in class `TokenStream`
  Throws:
    `IOException`
