[aspectj-users] Using reflection to get all ITD Methods

[Eduardo Piveta <piveta@xxxxxxxxx>]

Hi,

I'm using the 'getDeclaredITDMethods' method (available in the
reflection api) to find all ITD methods in the Billing aspect (from
the aspectj examples).

The Billing aspect contains 4 ITD methods (Connection.callRate,
LongDistance.callRate, Local.callRate and Customer.addCharge), but I
got only 3 of them using this method.

The 'Connection.callRate' is not returned by the
'getDeclaredITDMethods' method (maybe because it is abstract). In the
implementation of method 'getDeclaredITDMethods' in
'org.aspectj.internal.lang.reflect.AjTypeImpl' there is the following
condition:

if (!m.getName().contains("ajc$interMethod$")) continue;

Looking the names in the debbuger, I could not find a:
public static long
telecom.Billing.ajc$interMethod$telecom_Billing$telecom_Connection$callRate(telecom.Connection)
But only:
public static long
telecom.Billing.ajc$interMethodDispatch1$telecom_Billing$telecom_Connection$callRate(telecom.Connection)

if a take a concrete method, I get two objects, named:
public static long
telecom.Billing.ajc$interMethod$telecom_Billing$telecom_LongDistance$callRate(telecom.LongDistance)
public static long
telecom.Billing.ajc$interMethodDispatch1$telecom_Billing$telecom_LongDistance$callRate(telecom.LongDistance)

One of them satisfies the predicate !m.getName().contains("ajc$interMethod$").

Is this behavior correct?

ps.: I'm using the example bellow.

----------------------------------------------------------------
public aspect Billing {
    ...
    public abstract long Connection.callRate();
    public long LongDistance.callRate() { return LONG_DISTANCE_RATE; }
    public long Local.callRate() { return LOCAL_RATE; }
    public void Customer.addCharge(long charge){
        totalCharge += charge;
    }
    ...
}

----------------------------------------------------------------------------------------
import org.aspectj.lang.reflect.AjType;
import org.aspectj.lang.reflect.AjTypeSystem;
import org.aspectj.lang.reflect.InterTypeMethodDeclaration;

import telecom.Billing;

public class Test {
	public static void main(String args[]) throws ClassNotFoundException{
		AjType c = AjTypeSystem.getAjType(Billing.class);
		InterTypeMethodDeclaration[] itdmethods = c.getDeclaredITDMethods();
		for (int i = 0; i < itdmethods.length; i++) {
			System.out.println("ITD Method:" +
itdmethods[i].getTargetType().getName()+"."+itdmethods[i].getName());
		}		
	}
}
----------------------------------------------------------------
Output:
  ITD Method:telecom.LongDistance.callRate
  ITD Method:telecom.Local.callRate
  ITD Method:telecom.Customer.addCharge

Expected Output:
  ITD Method:telecom.Connection.callRate
  ITD Method:telecom.LongDistance.callRate
  ITD Method:telecom.Local.callRate
  ITD Method:telecom.Customer.addCharge

I'm using ajde 1.5.0.20051014142856.
