How to set ShapeNode as value of Data (data.type) ?

Question

Hi all,

I want to create Data with value which is a ShapeNode instead of String content. How can I do it ?

Sample:

<data key="d0">
    <y:ShapeNode>
        <y:NodeLabel>Node Label</y:NodeLabel>
        <y:Shape type="circle"/>
        <y:Fill color="#00FF00" transparent="false"/>
        <y:Geometry height="10" width="10" x="0" y="0"/>
    </y:ShapeNode>
</data>

Currently I tried to generate pojo classes from ygraphml.xsd schema by jaxb (jxc) then use those classes to create graphml file. Look into the class DataType, I just see it support method to set String content only.

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "data.type", namespace = "http://graphml.graphdrawing.org/xmlns")
public class DataType
    extends DataExtensionType

....

@XmlAccessorType(XmlAccessType.FIELD)
@XmlType(name = "data-extension.type", namespace = "http://graphml.graphdrawing.org/xmlns")
@XmlSeeAlso({
    DefaultType.class,
    DataType.class
})
public class DataExtensionType
    extends OriginalDataExtensionType

....

 

public class OriginalDataExtensionType {

    @XmlValue
    protected String content;

 

Therefore I cannot set ShapeNode as value of DataType.

Well, the ygraphml.xsd is probably too complex for automated POJO generation with  JAXB. (It uses inheritance - a feature that is not supported by most XML tools.) I guess you will have to resort to a more traditional approach to XML creation like Java's org.w3c.dom API.
