    Constructor and Description
    `InputIteratorWrapper(BytesRefIterator wrapped)` Creates a new wrapper, wrapping the specified iterator and specifying a weight value of `1` for all terms and nullifies associated payloads.

    All Methods Instance Methods Concrete Methods
    Modifier and Type | Method and Description
    --- | ---
    `Set<BytesRef>` | `contexts()` A term's contexts context can be used to filter suggestions.
    `boolean` | `hasContexts()` Returns true if the iterator has contexts
    `boolean` | `hasPayloads()` Returns true if the iterator has payloads
    `BytesRef` | `next()`
    `BytesRef` | `payload()` An arbitrary byte[] to record per suggestion.
    `long` | `weight()` A term's weight, higher numbers mean better suggestions.

    - #### InputIteratorWrapper

          public InputIteratorWrapper(BytesRefIterator wrapped)

      Creates a new wrapper, wrapping the specified iterator and specifying a weight value of `1` for all terms and nullifies associated payloads.

  - ### Method Detail

    - #### weight

          public long weight()

      Description copied from interface: `InputIterator`
      A term's weight, higher numbers mean better suggestions.
      Specified by:
        `weight` in interface `InputIterator`

    - #### next

          public BytesRef next()
                        throws IOException

      Specified by:
        `next` in interface `BytesRefIterator`
      Throws:
        `IOException`

    - #### payload

          public BytesRef payload()

      Description copied from interface: `InputIterator`
      An arbitrary byte[] to record per suggestion. See `Lookup.LookupResult.payload` to retrieve the payload for each suggestion.
      Specified by:
        `payload` in interface `InputIterator`

    - #### hasPayloads

          public boolean hasPayloads()

      Description copied from interface: `InputIterator`
      Returns true if the iterator has payloads
      Specified by:
        `hasPayloads` in interface `InputIterator`

    - #### contexts

          public Set<BytesRef> contexts()

      Description copied from interface: `InputIterator`
      A term's contexts context can be used to filter suggestions. May return null, if suggest entries do not have any context
      Specified by:
        `contexts` in interface `InputIterator`

    - #### hasContexts

          public boolean hasContexts()

      Description copied from interface: `InputIterator`
      Returns true if the iterator has contexts
      Specified by:
        `hasContexts` in interface `InputIterator`
