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

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)
