All Implemented Interfaces:

JavaType

Direct Known Subclasses:

MutableValueClassType, WrapperClassType

public class ValueClassType
extends PredefinedType

A ValueClassType instance represents a class whoses values may be treated as values rather than refernces during storing.

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

Since:

JDO 1.0.1

Constructor Detail

ValueClassType

public ValueClassType(java.lang.Class clazz,
              JavaType superclass,
              boolean orderable)

Constructor.

Parameters:

clazz - the Class instance representing the type

superclass - JavaType instance representing the superclass.

orderable - flag indicating whether this type is orderable.

Method Detail

Returns:

true if this JavaType represents a value type; false otherwise.

isOrderable

public boolean isOrderable()

Returns true if this JavaType represents an orderable type as specified by JDO.

Specified by:

isOrderable in interface JavaType

Overrides:

isOrderable in class AbstractJavaType

Returns:

true if this JavaType represents an orderable type; false otherwise.
