Throws:
  `IOException`

Method Detail

### getPayloads

    public void getPayloads(Spans[] subSpans)
                     throws IOException

  Throws:
    `IOException`

### processPayloads

    protected void processPayloads(Collection<byte[]> payLoads,
                                   int start,
                                   int end)

  By default, uses the `PayloadFunction` to score the payloads, but can be overridden to do other things.

  Parameters:
    `payLoads` - The payloads
    `start` - The start position of the span being scored
    `end` - The end position of the span being scored

    `Spans`

### setFreqCurrentDoc

    protected boolean setFreqCurrentDoc()
                                 throws IOException

  Overrides:
    `setFreqCurrentDoc` in class `SpanScorer`
  Throws:
    `IOException`

### score

    public float score()
                throws IOException

  Description copied from class: `Scorer`
  Returns the score of the current document matching the query. Initially invalid, until `DocIdSetIterator.nextDoc()` or `DocIdSetIterator.advance(int)` is called the first time, or when called from within `Collector.collect(int)`.

  Overrides:
    `score` in class `SpanScorer`
  Throws:
    `IOException`
