Class FloatDocValuesField
java.lang.Object
org.apache.lucene.document.Field
org.apache.lucene.document.NumericDocValuesField
org.apache.lucene.document.FloatDocValuesField
- All Implemented Interfaces:
- IndexableField
public class FloatDocValuesField
- extends NumericDocValuesField
Syntactic sugar for encoding floats as NumericDocValues
via Float.floatToRawIntBits(float)
.
Per-document floating point values can be retrieved via
FieldCache.getFloats(AtomicReader, String, boolean)
.
NOTE: In most all cases this will be rather inefficient,
requiring four bytes per document. Consider encoding floating
point values yourself with only as much precision as you require.
