Method Detail

toNativeType

public Object toNativeType(Object val)

Description copied from class: FieldType

Converts any Object to a java Object native to this field type

Overrides:

toNativeType in class FieldType

getSingleValueSource

protected ValueSource getSingleValueSource(SortedSetSelector.Type choice,
                               SchemaField f)

Description copied from class: TrieField

Helper method that will only be called for multivalued Trie fields that have doc values. Default impl throws an error indicating that selecting a single value from this multivalued field is not supported for this field type

Overrides:

getSingleValueSource in class TrieField

Parameters:

choice - the selector Type to use, will never be null

f - the field to use, garunteed to be multivalued.
