public class PointType
A point type that indexes a point in an n-dimensional space as separate fields and supports range queries.
See LatLonType
for geo-spatial queries.

IndexableField |
createField(SchemaField field,
Object value,
float boost)
It never makes sense to create a single field, so make it impossible to happen by throwing UnsupportedOperationException |
IndexableField[] |
createFields(SchemaField field,
Object value,
float boost)
Given a SchemaField , create one or more IndexableField instances |
Query |
createSpatialQuery(QParser parser,
SpatialOptions options)
Calculates the range and creates a RangeQuery (bounding box) wrapped in a BooleanQuery (unless the dimension is 1, one range for every dimension, AND'd together by a Boolean |
Query |
getFieldQuery(QParser parser,
SchemaField field,
String externalVal)
Throws UnsupportedOperationException() |
Query |
getRangeQuery(QParser parser,
SchemaField field,
String part1,
String part2,
boolean minInclusive,
boolean maxInclusive)
Returns a Query instance for doing range searches on this field type. |
SortField |
getSortField(SchemaField field,
boolean top)
Returns the SortField instance that should be used to sort fields of this type. |
ValueSource |
getValueSource(SchemaField field,
QParser parser)
called to get the default value source (normally, from the Lucene FieldCache.) |
protected void |
init(IndexSchema schema,
Map<String,String> args)
subclasses should initialize themselves with the args provided and remove valid arguments. |
boolean |
isPolyField()
A "polyField" is a FieldType that can produce more than one IndexableField instance for a single value, via the FieldType.createFields(org.apache.solr.schema.SchemaField, Object, float) method. |
void |
write(TextResponseWriter writer,
String name,
IndexableField f)
calls back to TextResponseWriter to write the field value |

FieldType
SolrQueryParser
currently passes part1 and part2 as null if they are '*' respectively. minInclusive and maxInclusive are both true
currently by SolrQueryParser but that may change in the future. Also, other QueryParser implementations may have
different semantics.
Sub-classes should override this method to provide their own range query implementation. They should strive to
handle nulls in part1 and/or part2 as well as unequal minInclusive and maxInclusive parameters gracefully.
