Class MapXmlPropertyDefConfigAdapter

java.lang.Object

javax.xml.bind.annotation.adapters.XmlAdapter<MapXmlPropertyDefConfigAdapter.ListProperty,Map<String,XmlPropertyDefConfig>>

org.azyva.dragom.model.config.impl.xml.MapXmlPropertyDefConfigAdapter

public class MapXmlPropertyDefConfigAdapter
extends XmlAdapter<MapXmlPropertyDefConfigAdapter.ListProperty,Map<String,XmlPropertyDefConfig>>

XmlAdapter for mapping the Map of XmlPropertyDefConfig in XmlNodeConfig to a simple list parameters in the XML file since JAXB does not directly support Map's, but mostly so that properties can be expressed with simple parameters.

By "simple parameters" we mean something convenient like this:

 
 <A_PROPERTY>a_value</A_PROPERTY>
 
 

instead of the more strict and verbose:

 
 <property>
   <name>A_PROPERTY</name>
   <value>a_value</value>
 </property>
 
 

or:

 
 <property name="A_PROPERTY" value="a_value"/>
 
 

Note that this makes specifying the indOnlyThisChild property of the XmlPropertyDefConfig more awkward, but nevertheless supported using an attribute:

 
 <A_PROPERTY ind-only-this-node="true">a_value</A_PROPERTY>

marshal

public MapXmlPropertyDefConfigAdapter.ListProperty marshal(Map<String,XmlPropertyDefConfig> mapPropertyDefConfigXml)

TODO: This method is not really useful for now since modification of XmlConfig is not currently supported.

In fact this method is incomplete as it does not support the indOnlyThisNode property which must be marshalled as an attribute of the property.

I believe the solution revolves around:

• Making the type of listProperty org.w3c.dom.Node instead of JAXBelement;
• Using DocumentBuilderFactory (.newInstance()) to build a Node representing property with the correct attribute.
