/**
   * init most recent FieldInfos for the current commit
   */
private FieldInfos initFieldInfos() throws IOException {
    if (!si.hasFieldUpdates()) {
        return core.coreFieldInfos;

}

Example 2 with FieldInfosFormat

use of org.apache.lucene.codecs.FieldInfosFormat in project lucene-solr by apache.

the class IndexWriter method readFieldInfos.

// reads latest field infos for the commit
// this is used on IW init and addIndexes(Dir) to create/update the global field map.
// TODO: fix tests abusing this method!

    Codec codec = si.info.getCodec();
    FieldInfosFormat reader = codec.fieldInfosFormat();
    if (si.hasFieldUpdates()) {
