[aspectj-users] Initializing inherited instance variables

[Aaron Blishen <aaron_blishen@xxxxxxxxx>]

Hi,

Im am trying to implement logging aspects that can be
customized on a class level basis.  I have something
on the lines of:

public abstract aspect LoggingAspect
{
  // log4j logger
  protected Log log;

  // call depth per log
  protected int callDepth;
	
  // Classes left unspecified
  public abstract pointcut cutClass(Object o);
	
	
  // Constructors in classes
  protected pointcut cutConstructor(Object o) :
    cutClass(o) && 
    execution (new(..)) && !within(LoggingAspect+);
		
  // Methods in classes
  protected pointcut cutMethod(Object o) : 
    cutClass(o) &&
    execution (* * (..)) && !within(LoggingAspect+);
		
	
  before (Object o): cutConstructor(o)
  {
    if(log.isDebugEnabled()) {
	log.debug(logConstruction(thisJoinPoint, o));
    }
  }
	
  before (Object o): cutMethod(o)
  {
    if(log.isDebugEnabled()) {
      log.debug(logBefore(thisJoinPoint, o));
    }
  }
	
  after (Object o): cutMethod(o)
  {
    if(log.isDebugEnabled()) {
	log.debug(logAfter(thisJoinPoint, o));
    }
  }
	
  after (Object o) throwing(Exception e) : 
    cutMethod(o)
  {
    if(log.isDebugEnabled()) {
      log.debug(logException(thisJoinPoint, e, o));
    }
  }
  ...
  // log helper methods
}

public aspect CustomLog extends LoggingAspect
{
  // compiler complains	
  callDepth = 2;
  log 	    = LogFactory.getLog(CustomLog.class);

  // only log certain packages
  public pointcut cutClass(Object o) : 
this(o)
		&& within(oracle.apps.ctb.admin.encounter.*);
		
}
