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

Modifier and Type	Method	Description
void	add(BytesRef utf8)	Adds a single suggestion entry (possibly compound with its bucket).
Comparator<BytesRef>	getComparator()	Comparator used to determine the sort order of entries.
BytesRefIterator	iterator()	Sorts the entries added in add(BytesRef) and returns an iterator over all sorted entries.

Method Details

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()

Comparator used to determine the sort order of entries.
