Interface BytesRefSorter

All Known Implementing Classes:
  ExternalRefSorter, InMemorySorter

    public interface BytesRefSorter

Collects `BytesRef` and then allows one to iterate over their sorted order. Implementations of this interface will be called in a single-threaded scenario.

WARNING: This API is experimental and might change in incompatible ways in the next release.
NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.

Method Summary
`void` | `add(BytesRef utf8)` Adds a single suggestion entry (possibly compound with its bucket).
`Comparator<BytesRef>` | `getComparator()`
`BytesRefIterator` | `iterator()` Sorts the entries added in `add(BytesRef)` and returns an iterator over all sorted entries.

Method Detail

### add

    void add(BytesRef utf8)
             throws IOException,
                    IllegalStateException

  Adds a single suggestion entry (possibly compound with its bucket).

  Throws:
    `IOException` - If an I/O exception occurs.
    `IllegalStateException` - If an addition attempt is performed after a call to `iterator()` has been made.

### iterator

    BytesRefIterator iterator()
                              throws IOException

  Sorts the entries added in `add(BytesRef)` and returns an iterator over all sorted entries.

  Throws:
    `IOException` - If an I/O exception occurs.

### getComparator

    Comparator<BytesRef> getComparator()
