Class org.apache.lucene.codecs.DocValuesFormat

Examples of org.apache.lucene.codecs.DocValuesFormat.fieldsProducer()

org.apache.lucene.codecs.DocValuesFormat.fieldsProducer()
Returns a {@link DocValuesProducer} to read docvalues from the index.
NOTE: by the time this call returns, it must hold open any files it will need to use; else, those files may be deleted. Additionally, required files may be deleted during the execution of this call before there is a chance to open them. Under these circumstances an IOException should be thrown by the implementation. IOExceptions are expected and will automatically cause a retry of the segment opening logic with the newly revised segments.

              final String suffix = fi.getAttribute(PER_FIELD_SUFFIX_KEY);
              assert suffix != null;
              DocValuesFormat format = DocValuesFormat.forName(formatName);
              String segmentSuffix = getFullSegmentSuffix(readState.segmentSuffix, getSuffix(formatName, suffix));
              if (!formats.containsKey(segmentSuffix)) {
                formats.put(segmentSuffix, format.fieldsProducer(new SegmentReadState(readState, segmentSuffix)));
              }
              fields.put(fieldName, formats.get(segmentSuffix));
            }
