Expert: This class provides a {@link TokenStream}
/// for indexing numeric values that can be used by {@link
/// NumericRangeQuery} or {@link NumericRangeFilter}.
///
/// Note that for simple usage, {@link NumericField} is
/// recommended. {@link NumericField} disables norms and
/// term freqs, as they are not usually needed during
/// searching. If you need to change these settings, you
/// should use this class.
///
/// See {@link NumericField} for capabilities of fields
/// indexed numerically.
///
/// Here's an example usage, for an int
field:
///
///
/// Field field = new Field(name, new NumericTokenStream(precisionStep).setIntValue(value));
/// field.setOmitNorms(true);
/// field.setOmitTermFreqAndPositions(true);
/// document.add(field);
///
///
/// For optimal performance, re-use the TokenStream and Field instance
/// for more than one document:
///
///
/// NumericTokenStream stream = new NumericTokenStream(precisionStep);
/// Field field = new Field(name, stream);
/// field.setOmitNorms(true);
/// field.setOmitTermFreqAndPositions(true);
/// Document document = new Document();
/// document.add(field);
///
/// for(all documents) {
/// stream.setIntValue(value)
/// writer.addDocument(document);
/// }
///
///
/// This stream is not intended to be used in analyzers;
/// it's more for iterating the different precisions during
/// indexing a specific numeric value.
///
/// NOTE: as token streams are only consumed once
/// the document is added to the index, if you index more
/// than one numeric field, use a separate NumericTokenStream
/// instance for each.
///
/// See {@link NumericRangeQuery} for more details on the
/// precisionStep
/// parameter as well as how numeric fields work under the hood.
///
/// NOTE: This API is experimental and
/// might change in incompatible ways in the next release.
///
