Constructor Detail

### InstantiatedTermPositions

    public InstantiatedTermPositions(InstantiatedIndexReader reader)

Method Detail

### getPayloadLength

    public int getPayloadLength()

  Specified by:
    `getPayloadLength` in interface `TermPositions`

### getPayload

    public byte[] getPayload(byte[] data,
                             int offset)
                      throws IOException

  Specified by:
    `getPayload` in interface `TermPositions`
  Throws:
    `IOException`

### isPayloadAvailable

    public boolean isPayloadAvailable()

  Specified by:
    `isPayloadAvailable` in interface `TermPositions`

### nextPosition

    public int nextPosition()

  Returns next position in the current document. It is an error to call this more than `InstantiatedTermDocs.freq()` times without calling `next()`

  This is invalid until `next()` is called for the first time.

  Specified by:
    `nextPosition` in interface `TermPositions`

### next

    public boolean next()

  Moves to the next pair in the enumeration.

  Returns true if there is such a next pair in the enumeration.

  Specified by:
    `next` in interface `TermDocs`
  Overrides:
    `next` in class `InstantiatedTermDocs`

### skipTo

    public boolean skipTo(int target)

  Skips entries to the first beyond the current whose document number is greater than or equal to target.

  Returns true iff there is such an entry.

  Behaves as if written:

         boolean skipTo(int target) {
           do {
             if (!next())
                   return false;
           } while (target > doc());
           return true;
         }

  Some implementations are considerably more efficient than that.

  Specified by:
    `skipTo` in interface `TermDocs`
  Overrides:
    `skipTo` in class `InstantiatedTermDocs`
