Class StringFieldType

java.lang.Object

org.elasticsearch.index.mapper.MappedFieldType

org.elasticsearch.index.mapper.SimpleMappedFieldType

org.elasticsearch.index.mapper.TermBasedFieldType

org.elasticsearch.index.mapper.StringFieldType

Direct Known Subclasses:

IgnoredFieldMapper.IgnoredFieldType, KeywordFieldMapper.KeywordFieldType, TextFieldMapper.TextFieldType

public abstract class StringFieldType
extends TermBasedFieldType

Base class for MappedFieldType implementations that use the same representation for internal index terms as the external representation so that partial matching queries such as prefix, wildcard and fuzzy queries can be implemented.
