public class DateRangeField
extends AbstractSpatialPrefixTreeFieldType<NumberRangePrefixTreeStrategy>
implements DateValueFieldType

A field for indexed dates and date ranges. It's mostly compatible with TrieDateField. It has the potential to allow efficient faceting, similar to facet.enum.

Method Detail

init

protected void init(IndexSchema schema,
                    Map<String,String> args)

Description copied from class: FieldType

subclasses should initialize themselves with the args provided and remove valid arguments. leftover arguments will cause an exception. Common boolean properties have already been handled.

Overrides:

init in class AbstractSpatialPrefixTreeFieldType<NumberRangePrefixTreeStrategy>

newPrefixTreeStrategy

protected NumberRangePrefixTreeStrategy newPrefixTreeStrategy(String fieldName)

Specified by:

newPrefixTreeStrategy in class AbstractSpatialPrefixTreeFieldType<NumberRangePrefixTreeStrategy>

createFields

public List<IndexableField> createFields(SchemaField field,
                                         Object val,
                                         float boost)

Description copied from class: FieldType

Given a SchemaField, create one or more IndexableField instances

Overrides:

createFields in class AbstractSpatialFieldType<NumberRangePrefixTreeStrategy>

Parameters:

field - the SchemaField

val - The value to add to the field

boost - The boost to apply

Returns:

An array of IndexableField

See Also:

FieldType.createField(SchemaField, Object, float), FieldType.isPolyField()

getStoredValue

protected String getStoredValue(org.locationtech.spatial4j.shape.Shape shape,
                                String shapeStr)

Description copied from class: AbstractSpatialFieldType

Called by AbstractSpatialFieldType.createFields(SchemaField, Object, float) to get the stored value.

Overrides:

getStoredValue in class AbstractSpatialFieldType<NumberRangePrefixTreeStrategy>

shapeToString

public String shapeToString(org.locationtech.spatial4j.shape.Shape shape)

Description copied from class: AbstractSpatialFieldType

Returns a String version of a shape to be used for the stored value. The format can be selected using the initParam format={WKT|GeoJSON}

Overrides:

shapeToString in class AbstractSpatialFieldType<NumberRangePrefixTreeStrategy>

parseShape

public NumberRangePrefixTree.NRShape parseShape(String str)

Description copied from class: AbstractSpatialFieldType

Create a Shape from the input string

Overrides:

parseShape in class AbstractSpatialFieldType<NumberRangePrefixTreeStrategy>

parseMath

public Date parseMath(Date now,
                      String rawval)

For easy compatibility with DateMathParser.parseMath(Date, String).

parseSpatialArgs

protected SpatialArgs parseSpatialArgs(QParser parser,
                                       String externalVal)

Overrides:

parseSpatialArgs in class AbstractSpatialFieldType<NumberRangePrefixTreeStrategy>

getRangeQuery

public Query getRangeQuery(QParser parser,
                           SchemaField field,
                           String startStr,
                           String endStr,
                           boolean minInclusive,
                           boolean maxInclusive)

Description copied from class: FieldType

Returns a Query instance for doing range searches on this field type. 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.

Overrides:

getRangeQuery in class AbstractSpatialFieldType<NumberRangePrefixTreeStrategy>

Parameters:

parser - the QParser calling the method

field - the schema field

startStr - the lower boundary of the range, nulls are allowed.

endStr - the upper boundary of the range, nulls are allowed

minInclusive - whether the minimum of the range is inclusive or not

maxInclusive - whether the maximum of the range is inclusive or not

Returns:

a Query instance to perform range search according to given parameters
