Uses of FieldComparator in org.apache.lucene.search

Subclasses of FieldComparator in org.apache.lucene.search

Modifier and Type	Class and Description
static class	FieldComparator.ByteComparator Parses field's values as byte (using FieldCache.getBytes(org.apache.lucene.index.AtomicReader, java.lang.String, boolean) and sorts by ascending value
static class	FieldComparator.DocComparator Sorts by ascending docID
static class	FieldComparator.DoubleComparator Parses field's values as double (using FieldCache.getDoubles(org.apache.lucene.index.AtomicReader, java.lang.String, boolean) and sorts by ascending value
static class	FieldComparator.FloatComparator Parses field's values as float (using FieldCache.getFloats(org.apache.lucene.index.AtomicReader, java.lang.String, boolean) and sorts by ascending value
static class	FieldComparator.FloatDocValuesComparator Uses float index values to sort by ascending value
static class	FieldComparator.IntComparator Parses field's values as int (using FieldCache.getInts(org.apache.lucene.index.AtomicReader, java.lang.String, boolean) and sorts by ascending value
static class	FieldComparator.IntDocValuesComparator Loads int index values and sorts by ascending value.
static class	FieldComparator.LongComparator Parses field's values as long (using FieldCache.getLongs(org.apache.lucene.index.AtomicReader, java.lang.String, boolean) and sorts by ascending value
static class	FieldComparator.NumericComparator<T extends Number> Base FieldComparator class for numeric types
static class	FieldComparator.RelevanceComparator Sorts by descending relevance.
static class	FieldComparator.ShortComparator Parses field's values as short (using FieldCache.getShorts(org.apache.lucene.index.AtomicReader, java.lang.String, boolean) and sorts by ascending value
static class	FieldComparator.TermOrdValComparator Sorts by field's natural Term sort order, using ordinals.
static class	FieldComparator.TermOrdValDocValuesComparator Sorts by field's natural Term sort order, using ordinals; this is just like FieldComparator.TermValComparator except it uses DocValues to retrieve the sort ords saved during indexing.
static class	FieldComparator.TermValComparator Sorts by field's natural Term sort order.
static class	FieldComparator.TermValDocValuesComparator Sorts by field's natural Term sort order.
