All Implemented Interfaces:

JavaType

public class WrapperClassType
extends ValueClassType

A WrapperClassType instance represents a Java wrapper class type. There are eight Java wrapper class types: java.lang.Boolean, java.lang.Byte, java.lang.Short, java.lang.Integer, java.lang.Long, java.lang.Character, java.lang.Float, java.lang.Double.

Class PredefinedType provides public static final variables referring to the JavaType representation for wrapper class types.

Since:

JDO 1.0.1
