Method Detail

checkSchemaField

public void checkSchemaField(SchemaField field)

Description copied from class: FieldType

Check's SchemaField instances constructed using this field type to ensure that they are valid.

This method is called by the SchemaField constructor to check that its initialization does not violate any fundamental requirements of the FieldType. Subclasses may choose to throw a SolrException if invariants are violated by the SchemaField.

Overrides:

checkSchemaField in class FieldType

write

public void write(TextResponseWriter writer,
                  String name,
                  org.apache.lucene.index.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

getSortField

public org.apache.lucene.search.SortField getSortField(SchemaField field,
                                                       boolean top)

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.getStringSort(org.apache.solr.schema.SchemaField, boolean), FieldType.getNumericSort(org.apache.solr.schema.SchemaField, org.apache.solr.schema.NumberType, boolean)

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()

toExternal

public String toExternal(org.apache.lucene.index.IndexableField f)

Description copied from class: FieldType

Convert the stored-field format to an external (string, human readable) value

Overrides:

toExternal in class FieldType

See Also:

FieldType.toInternal(java.lang.String)

toObject

public ByteBuffer toObject(org.apache.lucene.index.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)

createField

public org.apache.lucene.index.IndexableField createField(SchemaField field,
                                                          Object val)

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

FieldType.toInternal(java.lang.String)
