Phase 1 - Provide MOXy annotation support equivalent to our XML metadata support

This phase of development involves providing MOXy annotation support equivalent to the existing EclipseLink XML metadata support

Annotations

The following annotations will be targeted in this phase:

Annotation	XML Metadata Tag	Package	Type	Field	Method
XmlReadOnly	read-only			X	X
XmlWriteOnly	write-only			X	X
XmlCDATA	cdata			X	X
XmlAccessMethods	xml-access-methods			X	X
XmlPaths	xml-elements			X	X
XmlNullPolicy	xml-null-policy			X	X
XmlIsSetNullPolicy	xml-is-set-null-policy			X	X
XmlIsSetParameters	n/a			X	X
XmlIsSetParameter	is-set-parameter			X	X

Example: XmlReadOnly annotation

Java Metadata

The following example will demonstrate how the XmlReadOnly annotation can be applied:

A property can be configured to be read-only via XML metadata as follows:

eclipselink-oxm.xml

<xml-attribute java-attribute="salary" read-only="true" />

The equivalent configured via annotations would look like:

org.example.Employee.java

package org.example;
 
public class Employee {
    @javax.xml.bind.annotation.XmlAttribute
    @org.eclipse.persistence.oxm.annotations.XmlReadOnly
    public String salary;
}
