Method Detail

toNativeType

public Object toNativeType(Object val)

Description copied from class: FieldType

Converts any Object to a java Object native to this field type

Overrides:

toNativeType in class FieldType

getPointRangeQuery

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

Specified by:

getPointRangeQuery in class PointField

toObject

public Object toObject(SchemaField sf,
                       BytesRef term)

Overrides:

toObject in class FieldType

toObject

public Object toObject(IndexableField f)

Description copied from class: FieldType

Convert the stored-field format to an external object.

Overrides:

toObject in class FieldType

See Also:

FieldType.toInternal(java.lang.String)

getExactQuery

protected Query getExactQuery(SchemaField field,
                              String externalVal)

Specified by:

getExactQuery in class PointField

getSetQuery

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

Overrides:

getSetQuery in class PointField

indexedToReadable

protected String indexedToReadable(BytesRef indexedForm)

Specified by:

indexedToReadable in class PointField

readableToIndexed

public void readableToIndexed(CharSequence val,
                              BytesRefBuilder result)

Description copied from class: FieldType

Given the readable value, return the term value that will match it. This method will modify the size and length of the result parameter and write from offset 0

Overrides:

readableToIndexed in class FieldType

getUninversionType

public UninvertingReader.Type getUninversionType(SchemaField sf)

Description copied from class: FieldType

If DocValues is not enabled for a field, but it's indexed, docvalues can be constructed on the fly (uninverted, aka fieldcache) on the first request to sort, facet, etc. This specifies the structure to use.

This method will not be used if the field is (effectively) uninvertible="false"

Specified by:

getUninversionType in class FieldType

Parameters:

sf - field instance

Returns:

type to uninvert, or null (to disallow uninversion for the field)

See Also:

SchemaField.isUninvertible()

getValueSource

public ValueSource getValueSource(SchemaField field,
                                  QParser qparser)

Description copied from class: FieldType

called to get the default value source (normally, from the Lucene FieldCache.)

Overrides:

getValueSource in class FieldType

getSingleValueSource

protected ValueSource getSingleValueSource(SortedNumericSelector.Type choice,
                                           SchemaField f)

Description copied from class: PointField

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

Specified by:

getSingleValueSource in class PointField

Parameters:

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

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

See Also:

FieldType.getSingleValueSource(MultiValueSelector,SchemaField,QParser)

createField

public IndexableField createField(SchemaField field,
                                  Object value)

Description copied from class: FieldType

Used for adding a document when a field needs to be created from a type and a string.

By default, the indexed value is the same as the stored value (taken from toInternal()). Having a different representation for external, internal, and indexed would present quite a few problems given the current Lucene architecture. An analyzer for adding docs would need to translate internal->indexed while an analyzer for querying would need to translate external->indexed.

The only other alternative to having internal==indexed would be to have internal==external. In this case, toInternal should convert to the indexed representation, toExternal() should do nothing, and createField() should *not* call toInternal, but use the external value and set tokenized=true to get Lucene to convert to the internal(indexed) form.

:TODO: clean up and clarify this explanation.

Overrides:

createField in class FieldType

See Also:

FieldType.toInternal(java.lang.String)

getStoredField

protected StoredField getStoredField(SchemaField sf,
                                     Object value)

Specified by:

getStoredField in class PointField
