Do you only have one type of aspect?
<class name="com.acme.PathAssociation">
<map-to xml="aspect"/>
<field name="property" type="com.acme.Property"
set-method="addProperty"/>
</class>
If you have other types of aspects...such as:
<aspect name="someOtherType" ...>
Then...no you'll need XSLT...we don't currently have built-in support
for choosing
a class based on attributes. It would be a nice and powerful feature
though.
To solve this problem many people use a wrapper class, such as:
public class Aspect {
public static final String PATH_ASSOCIATION = "pathAssociation";
private String _name = null;
private Aspect _instance = null;
public void setName(String name) {
_name = name;
getInstance();
}
public Aspect getInstance() {
if (_instance != null)
return _instance;
if (_name == null) return null;
if (_name.equals(PATH_ASSOCIATION)) {
_instance = new PathAssociation();
}
return _instance;
}
public void addProperty(Property property) {
if (_instance != null) {
_instance.addProperty(property);
}
}
}
You can make your wrappers as fancy or as simple as you need. It's a bit
more work, but it gives you quite a bit of control.
And of course your XSLT solution will also work nicely.
