All Implemented Interfaces:

java.io.Serializable, scala.Equals, scala.Product

public class CharType
extends HiveStringType
implements scala.Product, scala.Serializable

Hive char type. Similar to other HiveStringType's, these datatypes should only used for parsing, and should NOT be used anywhere else. Any instance of these data types should be replaced by a StringType before analysis.
