Is there any API to fetch the internal names of all the soft attributes available on a type say "wt.part.WTPart"?

I have used the following code to get the IBA internal names.

------------------------------------------------------------

ArrayList<String> result = new ArrayList<String>();

TypeIdentifier identifier = TypedUtility.getTypeIdentifier(typeDef);

TypeDefinitionReadView typeDefView = TypeDefinitionServiceHelper.service.getTypeDefView(identifier);

for (AttributeDefinitionReadView attDef : typeDefView.getAllAttributes()) {

AttributeDefDefaultView ibaRefView = attDef.getIBARefView();

if (ibaRefView != null) {

result.add(ibaRefView.getLogicalIdentifier());

}
