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

getEnumMapping

public AbstractEnumField.EnumMapping getEnumMapping()

toObject

public EnumFieldValue 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)

getSortField

public 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)

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

Overrides:

getValueSource in class FieldType

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:
