Class FlagEnumerator

java.lang.Object

org.apache.lucene.analysis.hunspell.FlagEnumerator

class FlagEnumerator
extends Object

A structure similar to BytesRefHash, but specialized for sorted char sequences used for Hunspell flags. It deduplicates flag sequences, gives them unique ids, stores the sequences in a contiguous char[] (via finish() and allows to query presence of the flags later via FlagEnumerator.Lookup.hasFlag(int, char).
