BytesRefFieldSource
An implementation for retrieving
FunctionValues instances for string based fields. |
class |
DoubleFieldSource
Obtains double field values from
LeafReader.getNumericDocValues(java.lang.String) and makes
those values available as other numeric types, casting as needed. |
class |
EnumFieldSource
Obtains int field values from
LeafReader.getNumericDocValues(java.lang.String) and makes
those values available as other numeric types, casting as needed. |
class |
FloatFieldSource
Obtains float field values from
LeafReader.getNumericDocValues(java.lang.String) and makes those
values available as other numeric types, casting as needed. |
class |
IntFieldSource
Obtains int field values from
LeafReader.getNumericDocValues(java.lang.String) and makes those
values available as other numeric types, casting as needed. |
class |
JoinDocFreqValueSource

LeafReader.getSortedNumericDocValues(java.lang.String) and using a
SortedNumericSelector it gives a single-valued ValueSource view of a field. |
class |
MultiValuedLongFieldSource
Obtains long field values from
LeafReader.getSortedNumericDocValues(java.lang.String) and using a
SortedNumericSelector it gives a single-valued ValueSource view of a field. |
class |
