Re: [aspectj-users] true & false literals in type expressions?
> Is there a type _expression_ meaning "true" or "false"?

The pointcut component you could use is if(true) or if(false). Which I know internally are optimized to true/false - but I think the declare warning checking code currently polices that you can't use if  in deow - it should probably make an exception for if(true)/if(false) because we know they are special.

Is there a type _expression_ meaning "true" or "false"?  What I'd like is to be able to use the primitive literal values "true" & "false" in a type _expression_.  I'd like to replace the use of Bool in the example below with the literals.

public final aspect Bool {
  public static final pointcut true_(): within(*);
  public static final pointcut false_(): !true_();
}
=====
public abstract aspect Super {

  public abstract pointcut qualifyingUsage();

  public pointcut warnOnBadUseOfAnnotation():  Bool.false_();

  declare warning:
    warnOnBadUseOfAnnotation() && qualifyingUsage():
    "incorrect usage of annotation";
}
=====
public aspect Sub {
  public warnOnBadUseOfAnnotation():  Bool.true_();

  public pointcut qualifyingUsage():
    @NotSerializable Serializable+;
}
