Project Overview
Currently, EclipseLink MOXy supports the mapping of Java fields and properties to XML. Said another way; in order to map data to XML, the user must have an existing Java field or property to map.
To support multi-tenancy, we will be allowing the user to add additional mappings at runtime. Because these new mappings would not have existing fields / properties on the Java class to map to, we will instead introduce the concept of a "flex field", where we can map the elements of a Java Map to XML.
Example
@XmlRootElement public class Customer { @XmlAttribute private String name; @XmlExtensions private Map<String, Object> }
