See: Description

Interface Summary

Interface	Description
DomHandler<ElementT,ResultT extends Result>	Converts an element (and its descendants) from/to DOM (or similar) representation.

Class Summary

Class	Description
W3CDomHandler	DomHandler implementation for W3C DOM (org.w3c.dom package.)
XmlElement.DEFAULT	Used in XmlElement.type() to signal that the type be inferred from the signature of the property.
XmlElementDecl.GLOBAL	Used in XmlElementDecl.scope() to signal that the declaration is in the global scope.
XmlElementRef.DEFAULT	Used in XmlElementRef.type() to signal that the type be inferred from the signature of the property.
XmlSchemaType.DEFAULT	Used in XmlSchemaType.type() to signal that the type be inferred from the signature of the property.
XmlType.DEFAULT	Used in XmlType.factoryClass() to signal that either factory mehod is not used or that it's in the class with this XmlType itself.

Enum Summary

Enum	Description
XmlAccessOrder	Used by XmlAccessorOrder to control the ordering of properties and fields in a JAXB bound class.
XmlAccessType	Used by XmlAccessorType to control serialization of fields or properties.
XmlNsForm	Enumeration of XML Schema namespace qualifications.

Annotation Types Summary

Annotation Type	Description

XmlInlineBinaryData	Disable consideration of XOP encoding for datatypes that are bound to base64-encoded binary data in XML.
XmlList	Used to map a property to a list simple type.
XmlMimeType	Associates the MIME type that controls the XML representation of the property.
XmlMixed	Annotate a JavaBean multi-valued property to support mixed content.
XmlNs	Associates a namespace prefix with a XML namespace URI.
XmlRegistry	Marks a class that has XmlElementDecls.
XmlRootElement	Maps a class or an enum type to an XML element.
XmlSchema	Maps a package name to a XML namespace.
XmlSchemaType	Maps a Java type to a simple schema built-in type.
XmlSchemaTypes	A container for multiple @XmlSchemaType annotations.
XmlSeeAlso	Instructs JAXB to also bind other classes when binding this class.
XmlTransient	Prevents the mapping of a JavaBean property/type to XML representation.
XmlType	Maps a class or an enum type to a XML Schema type.
XmlValue	Enables mapping a class to a XML Schema complex type with a simpleContent or a XML Schema simple type.

Package javax.xml.bind.annotation Description

Defines annotations for customizing Java program elements to XML Schema mapping.

Package Specification

The following table shows the JAXB mapping annotations that can be associated with each program element.

Program Element	JAXB annotation
Package	XmlAccessorOrder XmlAccessorType XmlSchema XmlSchemaType XmlSchemaTypes XmlJavaTypeAdapter XmlJavaTypeAdapters
Class	XmlAccessorOrder XmlAccessorType XmlInlineBinaryData XmlRootElement XmlType XmlJavaTypeAdapter
Enum type	XmlEnum XmlEnumValue (enum constant only) XmlRootElement XmlType XmlJavaTypeAdapter
JavaBean Property/field	XmlElement XmlElements XmlElementRef XmlElementRefs XmlElementWrapper XmlAnyElement XmlAttribute XmlAnyAttribute XmlTransient XmlValue XmlID XmlIDREF XmlList XmlMixed XmlMimeType XmlAttachmentRef XmlInlineBinaryData XmlElementDecl (only on method) XmlJavaTypeAdapter
Parameter	XmlList XmlAttachmentRef XmlMimeType XmlJavaTypeAdapter

Terminology

JavaBean property and field: For the purposes of mapping, there is no semantic difference between a field and a JavaBean property. Thus, an annotation that can be applied to a JavaBean property can always be applied to a field. Hence in the Javadoc documentation, for brevity, the term JavaBean property or property is used to mean either JavaBean property or a field. Where required, both are explicitly mentioned.

top level class: For the purpose of mapping, there is no semantic difference between a top level class and a static nested class. Thus, an annotation that can be applied to a top level class, can always be applied to a nested static class. Hence in the Javadoc documentation, for brevity, the term "top level class" or just class is used to mean either a top level class or a nested static class.

mapping annotation:A JAXB 2.0 defined program annotation based on the JSR 175 programming annotation facility.

Common Usage Constraints

The following usage constraints are defined here since they apply to more than annotation:

• For a property, a given annotation can be applied to either read or write property but not both.
• A property name must be different from any other property name in any of the super classes of the class being mapped.
• A mapped field name or the decapitalized name of a mapped property must be unique within a class.

Notations

Namespace prefixes

The following namespace prefixes are used in the XML Schema fragments in this package.

Prefix	Namespace	Notes
xs	http://www.w3.org/2001/XMLSchema	Namespace of XML Schema namespace
ref	http://ws-i.org/profiles/basic/1.1/xsd	Namespace for swaref schema component
xsi	http://www.w3.org/2001/XMLSchema-instance	XML Schema namespace for instances
