public class MakeDirty
extends ClassMethod

Method to generate the method "dnMakeDirty" using ASM.

 public void dnMakeDirty(String fieldName)
 {
     if (dnStateManager != null)
         dnStateManager.makeDirty(this, fieldName);
     if (dnIsDetached() && fieldName != null) 
     {
         String fldName = null;
         if (fieldName.indexOf('.') ≥ 0)
             fldName = fieldName.substring(fieldName.lastIndexOf('.') + 1);
         else
             fldName = fieldName;
         for (int i = 0; i < dnFieldNames.length; i++) 
         {
             if (dnFieldNames[i].equals(fldName)) 
             {
                 if (((BitSet) dnDetachedState[2]).get(i + dnInheritedFieldCount))
                     ((BitSet) dnDetachedState[3]).set(i + dnInheritedFieldCount);
                 else
                     throw new JDODetachedFieldAccessException("You have just attempted to access a field/property");
                 break;
             }
         }
     }
 }
 

and if not detachable

public void dnMakeDirty(String fieldName)
 {
     if (dnStateManager != null)
         dnStateManager.makeDirty(this, fieldName);
 }
 

TODO This currently doesnt cater for a fully-qualified field where the class name part doesnt define a field at that level
