Map attributes in xstream

We have to write converter.

package com.xstream;
 
import com.thoughtworks.xstream.annotations.XStreamAsAttribute;
 
public class Attribute {
 
  @XStreamAsAttribute
  private String name;
 
  private String value;
 
  public Attribute(String name, String value) {
    this.name = name;
    this.value = value;
  }
 
  /**
   * @return the name
   */
  public String getName() {
    return name;
  }
 
  /**
   * @param name the name to set
   */
  public void setName(String name) {
    this.name = name;
  }
 
  /**
   * @return the value
   */
  public String getValue() {
    return value;
  }
 
  /**
   * @param value the value to set
   */
  public void setValue(String value) {
    this.value = value;
  }
 
  /* (non−Javadoc)
   * @see java.lang.Object#toString()
   */
  @Override
  public String toString() {
    return "Attribute [name=" + name + ", value=" + value + "]";
  }
 
}

AttributeConverter class is:

package com.xstream;
 
import com.thoughtworks.xstream.converters.Converter;
import com.thoughtworks.xstream.converters.MarshallingContext;
import com.thoughtworks.xstream.converters.UnmarshallingContext;
import com.thoughtworks.xstream.io.HierarchicalStreamReader;
import com.thoughtworks.xstream.io.HierarchicalStreamWriter;
 
public class AttributeConverter implements Converter{
 
  @Override
  public boolean canConvert(Class clazz) {
    return clazz.equals(Attribute.class);
  }
 
  @Override
  public void marshal(Object object, HierarchicalStreamWriter writer, MarshallingContext context) {
    System.out.println("object = " + object.toString());
    Attribute attribute = (Attribute) object;
    writer.addAttribute("name", attribute.getName());  
    writer.setValue(attribute.getValue());  
 
  }
 
  @Override
  public Object unmarshal(HierarchicalStreamReader reader, UnmarshallingContext context) {
    return new Attribute(reader.getAttribute("name"), reader.getValue());
 
  } 
 
}

Use this in Qualification class as:

@XStreamConverter(AttributeConverter.class)
  private Attribute attribute;

Register converter in main class as:

xstream.registerConverter(new AttributeConverter());
