IndexableField |
createField(SchemaField field,
Object val,
float boost)
Used for adding a document when a field needs to be created from a
type and a string.
|
SortField |
getSortField(SchemaField field,
boolean top)
Returns the SortField instance that should be used to sort fields
of this type.
|
String |
toExternal(IndexableField f)
Convert the stored-field format to an external (string, human readable)
value
|
ByteBuffer |
toObject(IndexableField f)
Convert the stored-field format to an external object.
|
void |
write(TextResponseWriter writer,
String name,
IndexableField f)
calls back to TextResponseWriter to write the field value

FieldType
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.
