      org.apache.lucene.analysis.Analyzer.TokenStreamComponents

Enclosing class:
  Analyzer

    public static class Analyzer.TokenStreamComponents

extends Object

This class encapsulates the outer components of a token stream. It provides access to the source (`Tokenizer`) and the outer end (sink), an instance of `TokenFilter` which also serves as the `TokenStream` returned by `Analyzer.tokenStream(String, Reader)`.

Field Summary
`protected TokenStream` `sink` Sink tokenstream, such as the outer tokenfilter decorating the chain.
`protected Tokenizer` `source` Original source of the tokens.

Constructor Summary
`Analyzer.TokenStreamComponents(Tokenizer source)` Creates a new `Analyzer.TokenStreamComponents` instance.
`Analyzer.TokenStreamComponents(Tokenizer source, TokenStream result)` Creates a new `Analyzer.TokenStreamComponents` instance.

Method Summary
`Tokenizer` `getTokenizer()` Returns the component's `Tokenizer`
`TokenStream` `getTokenStream()` Returns the sink `TokenStream`
`protected void` `setReader(Reader reader)` Resets the encapsulated components with the given reader.

Field Detail

### source

    protected final Tokenizer source

  Original source of the tokens.

### sink

    protected final TokenStream sink

  Sink tokenstream, such as the outer tokenfilter decorating the chain. This can be the source if there are no filters.

Constructor Detail

### Analyzer.TokenStreamComponents

    public Analyzer.TokenStreamComponents(Tokenizer source,
                                          TokenStream result)

  Creates a new `Analyzer.TokenStreamComponents` instance.

  Parameters:
    `source` - the analyzer's tokenizer
    `result` - the analyzer's resulting token stream

### Analyzer.TokenStreamComponents

    public Analyzer.TokenStreamComponents(Tokenizer source)

  Creates a new `Analyzer.TokenStreamComponents` instance.

  Parameters:
    `source` - the analyzer's tokenizer

Method Detail

### setReader

    protected void setReader(Reader reader)
                      throws IOException

  Resets the encapsulated components with the given reader. If the components cannot be reset, an Exception should be thrown.

  Parameters:
    `reader` - a reader to reset the source component
  Throws:
    `IOException` - if the component's reset method throws an `IOException`

### getTokenStream

    public TokenStream getTokenStream()

  Returns the sink `TokenStream`

  Returns:
    the sink `TokenStream`

### getTokenizer

    public Tokenizer getTokenizer()

  Returns the component's `Tokenizer`

  Returns:
    Component's `Tokenizer`
