public class UUIDField
extends StrField

This FieldType accepts UUID string values, as well as the special value of "NEW" which triggers generation of a new random UUID.

NOTE: Configuring a UUIDField instance with a default value of "NEW" is not advisable for most users when using SolrCloud (and not possible if the UUID value is configured as the unique key field) since the result will be that each replica of each document will get a unique UUID value. Using UUIDUpdateProcessorFactory to generate UUID values when documents are added is recomended instead.

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 StrField

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.

Overrides:

getSortField in class StrField

See Also:

SchemaField.checkSortability()

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

Overrides:

write in class StrField

Throws:

IOException

toInternal

public String toInternal(String val)

Generates a UUID if val is either null, empty or "NEW". Otherwise it behaves much like a StrField but checks that the value given is indeed a valid UUID.

Overrides:

toInternal in class FieldType

Parameters:

val - The value of the field

See Also:

FieldType.toInternal(java.lang.String)

toInternal

public String toInternal(UUID uuid)

toObject

public UUID 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)
