Method Summary

Modifier and Type	Method and Description
List<IndexableField>	createFields(SchemaField field, Object value) Given a SchemaField, create one or more IndexableField instances
SortField	getSortField(SchemaField field, boolean reverse) Returns the SortField instance that should be used to sort fields of this type.
UninvertingReader.Type	getUninversionType(SchemaField sf) 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.
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.
Object	marshalSortValue(Object value) Convert a value used by the FieldComparator for this FieldType's SortField into a marshalable value for distributed sorting.
Object	toObject(SchemaField sf, BytesRef term)
Object	unmarshalSortValue(Object value) Convert a value marshaled via FieldType.marshalSortValue(java.lang.Object) back into a value usable by the FieldComparator for this FieldType's SortField
void	write(TextResponseWriter writer, String name, IndexableField f) calls back to TextResponseWriter to write the field value

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 PrimitiveFieldType

createFields

public List<IndexableField> createFields(SchemaField field,
                                         Object value)

Description copied from class: FieldType

Given a SchemaField, create one or more IndexableField instances

Overrides:

createFields in class FieldType

Parameters:

field - the SchemaField

value - The value to add to the field

Returns:

An array of IndexableField

See Also:

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

getSortField

public SortField getSortField(SchemaField field,
                              boolean reverse)

Description copied from class: FieldType

Returns the SortField instance that should be used to sort fields of this type.

Specified by:

getSortField in class FieldType

See Also:

SchemaField.checkSortability(), FieldType.getSortField(SchemaField,SortField.Type,boolean,Object,Object)

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.

Specified by:

getUninversionType in class FieldType

Parameters:

sf - field instance

Returns:

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

write

public void write(TextResponseWriter writer,
                  String name,
                  IndexableField f)
           throws IOException

Description copied from class: FieldType

calls back to TextResponseWriter to write the field value

Specified by:

write in class FieldType

Throws:

IOException

getValueSource

public ValueSource getValueSource(SchemaField field,
                                  QParser parser)

Description copied from class: FieldType

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

Overrides:

getValueSource in class FieldType

toObject

public Object toObject(SchemaField sf,
                       BytesRef term)

Overrides:

toObject in class FieldType

marshalSortValue

public Object marshalSortValue(Object value)

Description copied from class: FieldType

Convert a value used by the FieldComparator for this FieldType's SortField into a marshalable value for distributed sorting.

Overrides:

marshalSortValue in class FieldType

unmarshalSortValue

public Object unmarshalSortValue(Object value)

Description copied from class: FieldType

Convert a value marshaled via FieldType.marshalSortValue(java.lang.Object) back into a value usable by the FieldComparator for this FieldType's SortField

Overrides:

unmarshalSortValue in class FieldType
