Constructor Detail

• MockGraphTokenFilter

  public MockGraphTokenFilter​(Random random,
                              TokenStream input)

Method Detail

• newPosition

  protected LookaheadTokenFilter.Position newPosition()

  Specified by:

  newPosition in class LookaheadTokenFilter<LookaheadTokenFilter.Position>

• afterPosition

  protected void afterPosition()
                        throws IOException

  Description copied from class: LookaheadTokenFilter
  This is called when all input tokens leaving a given position have been returned. Override this and call createToken and then set whichever token's attributes you want, if you want to inject a token starting from this position.

  Overrides:

  afterPosition in class LookaheadTokenFilter<LookaheadTokenFilter.Position>

  Throws:

  IOException

• reset

  public void reset()
             throws IOException

  Description copied from class: TokenFilter
  Reset the filter as well as the input TokenStream.

  Overrides:

  reset in class LookaheadTokenFilter<LookaheadTokenFilter.Position>

  Throws:

  IOException

• incrementToken

  public boolean incrementToken()
                         throws IOException

  Description copied from class: TokenStream
  Consumers (i.e., IndexWriter) use this method to advance the stream to the next token. Implementing classes must implement this method and update the appropriate AttributeImpls with the attributes of the next token.

  The producer must make no assumptions about the attributes after the method has been returned: the caller may arbitrarily change it. If the producer needs to preserve the state for subsequent calls, it can use AttributeSource.captureState() to create a copy of the current attribute state.

  This method is called for every token of a document, so an efficient implementation is crucial for good performance. To avoid calls to AttributeSource.addAttribute(Class) and AttributeSource.getAttribute(Class), references to all AttributeImpls that this stream uses should be retrieved during instantiation.

  To ensure that filters and consumers know which attributes are available, the attributes must be added during instantiation. Filters and consumers are not required to check for availability of attributes in TokenStream.incrementToken().

  Specified by:

  incrementToken in class TokenStream

  Returns:

  false for end of stream; true otherwise

  Throws:

  IOException
