public abstract class PointField
extends NumericFieldType

Provides field types to support for Lucene's IntPoint, LongPoint, FloatPoint and DoublePoint. See PointRangeQuery for more details. It supports integer, float, long and double types. See subclasses for details.
DocValues are supported for single-value cases (NumericDocValues). FieldCache is not supported for PointFields, so sorting, faceting, etc on these fields require the use of docValues="true" in the schema.

Field Detail

TEST_HACK_IGNORE_USELESS_TRIEFIELD_ARGS

public static boolean TEST_HACK_IGNORE_USELESS_TRIEFIELD_ARGS

The Test framework can set this global variable to instruct PointField that (on init) it should be tollerant of the precisionStep argument used by TrieFields. This allows for simple randomization of TrieFields and PointFields w/o extensive duplication of <fieldType/> declarations.

NOTE: When TrieField is removed, this boolean must also be removed

WARNING: This API is experimental and might change in incompatible ways in the next release.

NOTE: This API is for internal purposes only and might change in incompatible ways in the next release.

Method Detail

init

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

NOTE: This method can be removed completely when TEST_HACK_IGNORE_USELESS_TRIEFIELD_ARGS is removed

Overrides:

init in class PrimitiveFieldType

isPointField

public boolean isPointField()

Overrides:

isPointField in class FieldType

getSingleValueSource

public final ValueSource getSingleValueSource(FieldType.MultiValueSelector choice,
                                              SchemaField field,
                                              QParser parser)

Description copied from class: FieldType

Method for dynamically building a ValueSource based on a single value of a multivalued field. The default implementation throws an error except in the trivial case where this method is used on a SchemaField that is in fact not-multivalued, in which case it delegates to FieldType.getValueSource(org.apache.solr.schema.SchemaField, org.apache.solr.search.QParser)

Overrides:

getSingleValueSource in class FieldType

See Also:

FieldType.MultiValueSelector

getSingleValueSource

protected abstract ValueSource getSingleValueSource(SortedNumericSelector.Type choice,
                                                    SchemaField field)

Helper method that will only be called for multivalued Point fields that have doc values. Default impl throws an error indicating that selecting a single value from this multivalued field is not supported for this field type

Parameters:

choice - the selector Type to use, will never be null

field - the field to use, guaranteed to be multivalued.

See Also:

FieldType.getSingleValueSource(MultiValueSelector,SchemaField,QParser)

isTokenized

public boolean isTokenized()

Description copied from class: FieldType

Returns true if fields of this type should be tokenized

Overrides:

isTokenized in class FieldType

multiValuedFieldCache

public boolean multiValuedFieldCache()

Description copied from class: FieldType

Returns true if a single field value of this type has multiple logical values for the purposes of faceting, sorting, etc. Text fields normally return true since each token/word is a logical value.

Overrides:

multiValuedFieldCache in class FieldType

getSetQuery

public Query getSetQuery(QParser parser,
                         SchemaField field,
                         Collection<String> externalVals)

Overrides:

getSetQuery in class FieldType

getFieldQuery

public Query getFieldQuery(QParser parser,
                           SchemaField field,
                           String externalVal)

Description copied from class: FieldType

Returns a Query instance for doing searches against a field.

Overrides:

getFieldQuery in class FieldType

Parameters:

parser - The QParser calling the method

field - The SchemaField of the field to search

externalVal - The String representation of the value to search

Returns:

The Query instance. This implementation returns a TermQuery but overriding queries may not

getExactQuery

protected abstract Query getExactQuery(SchemaField field,
                                       String externalVal)

getPointRangeQuery

public abstract Query getPointRangeQuery(QParser parser,
                                         SchemaField field,
                                         String min,
                                         String max,
                                         boolean minInclusive,
                                         boolean maxInclusive)

getRangeQuery

public Query getRangeQuery(QParser parser,
                           SchemaField field,
                           String min,
                           String max,
                           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 FieldType

Parameters:

parser - the QParser calling the method

field - the schema field

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

max - 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
