Document History
- April 26, 2013 - Initial Draft
Requirements
- Related Enhancement Request - bug 406697
- Required for JSON schema generation - JSON Schema Generation
API
The following annotation will be added
org.eclipse.persistence.oxm.annotations.XmlVariableNode
@Target({METHOD, FIELD}) @Retention(RUNTIME) public @interface XmlVariableNode { String attributeName(); }
Example
@XmlRootElement public class Root { public String name; @XmlVariableNode(attributeName="thingName") public List<Thing> things; } public class Thing { public String thingName; public String thingValue; }
Root r = new Root(); r.name = "theRootName"; r.things = new ArrayList<Thing>(); Thing thing1 = new Thing(); thing1.thingName = "thinga"; thing1.thingValue = "thingavalue"; Thing thing2 = new Thing(); thing2.thingName = "thingb"; thing2.thingValue = "thingbvalue"; Thing thing3 = new Thing(); thing3.thingName = "thingc"; thing3.thingValue = "thingcvalue"; r.things.add(thing1); r.things.add(thing2); r.things.add(thing3);
marshaller.marshal(r, System.out) XML <root> <name>theRootName</name> <thinga> <thingName>thinga</thingName> <thingValue>thingavalue</thingValue> </thinga> <thingb> <thingName>thingb</thingName> <thingValue>thingbvalue</thingValue> </thingb> <thingc> <thingName>thingc</thingName> <thingValue>thingcvalue</thingValue> </thingc> </root>
</source>
marshaller.marshal(r, System.out) JSON {"root":{ "name":"theRootName" "thinga":{ "thingName":"thinga" "thingValue":"thingavalue"}, "thingb":{ "thingName":"thingb" "thingValue":"thingbvalue"}, "thingc":{ "thingName":"thingc" "thingValue":"thingcvalue"} }}
Design
A new mapping will be created XMLVariableXPathMapping and it will extend the AnyCollectionMapping
Note/Issues
- inheritance
- List<Object>
- single case ie:not on a collection
- external bindings
- don`t write out that property itself as nested if it is the variable field - currently need to mark that property as transient.
