EclipseLink/Release/2.4.0/JAXB RI Extensions

Marshaller Features

Cycle Recoverable

Usage: Implement the com.sun.xml.bind.CycleRecoverable interface

Allows the user to write their own logic to be used when object cycles are detected during marshal operations.


Object Identitity Cycle Detection

Usage: marshaller.setProperty("com.sun.xml.bind.objectIdentitityCycleDetection", false);

Used to configure the strategy EclipseLink will use to detect an Object cycle. By default, EclipseLink will use Object identity to determine if a cycle exists; setting this property to false will tell EclipseLink to use the equals() method instead.

XML Declaration

Usage: marshaller.setProperty("com.sun.xml.bind.xmlDeclaration", true);

Allows the user to omit the XML processing instruction from marshalled documens. This property is the opposite of Marshaller.JAXB_FRAGMENT, and is included for backwards compatibility only.

XML Headers

Usage: marshaller.setProperty("com.sun.xml.bind.xmlHeaders", headerString);

Allows the user to supply a header string, which will appear after the XML processing instruction (<?xml ...>), but before the start of the document's data.

Indent String

Usage: marshaller.setProperty("com.sun.xml.bind.indentString", indentString);

      marshaller.setProperty(org.eclipse.persistence.jaxb.MarshallerProperties.INDENT_STRING, indentString);

Allows the user to override the indent string that is used when marshalling objects.

Character Escape Handler

Usage: marshaller.setProperty("com.sun.xml.bind.marshaller.CharacterEscapeHandler", new MyCharacterEscapeHandler());

      marshaller.setProperty(org.eclipse.persistence.jaxb.MarshallerProperties.CHARACTER_ESCAPE_HANDLER, new MyCharacterEscapeHandler());

Allows the user to provide their own character-escaping logic by supplying their own implementation of the CharacterEscapeHandler interface.


Unmarshaller Features

ID Resolver

Usage: unmarshaller.setProperty("com.sun.xml.bind.IDResolver", new MyIdResolver());

      unmarshaller.setProperty(org.eclipse.persistence.jaxb.UnmarshallerProperties.ID_RESOLVER, new MyIdResolver());

Allows the user to provide their own logic for resolving XML IDs/IDREFs.


XML Location

Usage: Annotate a property with @XmlLocation

Allows the user to specify a property on the JAXB object that will be updated (upon unmarshalling) with that object's XML location information (i.e. the line number, column number, and system ID that points to this object's location in the XML input).
