Class OffsetCharFilter

java.lang.Object
  java.io.Reader
      org.apache.lucene.analysis.CharFilter
          org.apache.lucene.analysis.charfilter.BaseCharFilter
              lux.index.analysis.OffsetCharFilter

All Implemented Interfaces:

Closeable, Readable

public class OffsetCharFilter
extends org.apache.lucene.analysis.charfilter.BaseCharFilter

exposes the offset map so it can be set externally. It seems as if it would be better to be able to reset() and reuse this? But we have to make a new BaseCharFilter for every text node.
