Class XMLRootConverter

java.lang.Object

org.eclipse.persistence.oxm.mappings.converters.XMLRootConverter

All Implemented Interfaces:

Serializable, CoreConverter<DatabaseMapping,Session>, Converter, XMLConverter

public class XMLRootConverter
extends Object
implements XMLConverter

Purpose: Provides an implementation of XMLConverter to wrap/unwrap objects in an XMLRoot in order to capture element name information.

Responsibilities

• Wrap an object in an XMLRoot on unmarshal. Do any required conversions based on type for simple mappings.
• Unwrap an XMLRoot from the object and pass it along to be marshalled.

                                            XMLUnmarshaller unmarshaller)

convertObjectValueToDataValue

public Object convertObjectValueToDataValue(Object objectValue,
                                            Session session,
                                            XMLMarshaller marshaller)

convertDataValueToObjectValue

public Object convertDataValueToObjectValue(Object dataValue,
                                            Session session)

Description copied from interface: Converter

PUBLIC: Convert the databases' data representation of the value to the object's representation. For example this could convert between an sql.Time datatype and the Java Calendar type.

convertObjectValueToDataValue

public Object convertObjectValueToDataValue(Object objectValue,

initialize

public void initialize(DatabaseMapping mapping,
                       Session session)

Description copied from interface: Converter

PUBLIC: Allow for any initialization.

isMutable

public boolean isMutable()

Description copied from interface: Converter

PUBLIC: If the converter converts the value to a mutable value, i.e. a value that can have its' parts changed without being replaced, then it must return true. If the value is not mutable, cannot be changed without replacing the whole value then false must be returned. This is used within the UnitOfWork to determine how to clone.
