All Implemented Interfaces:

JavaType

public class JDOSupportedCollectionType
extends PredefinedType

A JDOSupportedCollectionType instance represents a JDO supported collection type.

Class PredefinedType provides public static final variables referring to the JavaType representation for JDO supported map types.

Constructor Detail

JDOSupportedCollectionType

public JDOSupportedCollectionType(java.lang.Class clazz)

Constructor for JDOSupportedCollection types having no superclass. These are the collection interfaces among the JDO supported collection types.

Parameters:

clazz - the Class instance representing the type.

JDOSupportedCollectionType

public JDOSupportedCollectionType(java.lang.Class clazz,
                          JavaType superclass)

Constructor for JDOSupportedCollection types having a superclass. These are the collection implemenatation classes among the JDO supported collection types.

Parameters:

clazz - the Class instance representing the type

superclass - JavaType instance representing the superclass.

Method Detail

isJDOSupportedCollection

public boolean isJDOSupportedCollection()

Returns true if this JavaType represents a JDO supported collection type. The JDO specification allows the following collection interfaces and classes as types of persistent fields (see section 6.4.3 Persistent fields):

Specified by:

isJDOSupportedCollection in interface JavaType

Overrides:

isJDOSupportedCollection in class AbstractJavaType

Returns:

true if this JavaType represents a JDO supported collection; false otherwise.

isTrackable

public boolean isTrackable()

Returns true if this JavaType represents a trackable Java class. A JDO implementation may replace a persistent field of a trackable type with an assignment compatible instance of its own implementation of this type which notifies the owning FCO of any change of this field.

Specified by:

isTrackable in interface JavaType

Overrides:

isTrackable in class AbstractJavaType

Returns:

true if this JavaType represents a trackable Java class, false otherwise.
