Re: [aspectj-users] How to declare an error when implementations of an interface doesn't supply a certain constructor
|
Yes, you can send it to me and I'll try it - andrew.clement AT

Hi
No, it's basically the same code as yours (only the name of the broken
class differs).
Could I try and send it to you? I dunno if this mailling list will
allow attachments?

I cut my program from the previous email and pasted it
into an AspectJ project. AJDT version 1.3.0.20051220093604 running in
Eclipse 3.1.1 - and again it only flagged MyBrokenOption (all I did in
the AspectJ project was activate hasMember). there must be some
difference between your program and mine - do you define constructors
elsewhere in the hierarchy?

Hi
This is very strange. The same code in Eclipse 3.1.1 with the latest
AJDT 1.3 shows an error for MyXOption but not for MyBrokenOption.
I also tried under Eclipse 3.2M4 with the latest AJDT 1.4 and it
showed the same result.
Can anyone reproduce this under Eclipse?

Sorry if I've come
to this late and am missing some
context.... I typed in your program, added some missing types and added
a type that broke the rule:
-------------8<---------------
public aspect OptionAspect {
interface IBadOptionSubtype {};
declare parents : (IOption+ && !IOption &&
!IXOption && !IYOption && !IZOption) &&
!hasmethod(new(OptionType))
implements IBadOptionSubtype;
declare error : staticinitialization(IOption+ &&
IBadOptionSubtype+)
: "IOption implementations must provide a constructor which
accepts an OptionType";
}
interface IOption {}
interface IXOption extends IOption {}
interface IYOption extends IOption {}
interface IZOption extends IOption {}
class OptionType {}
class MyXOption implements IXOption {
public MyXOption(OptionType type) { }
}
class MyBrokenOption implements IXOption {
}
-----------------8<----------------
I then compiled it:
C:\aspectj1.5>ajc -XhasMember -showWeaveInfo OptionAspect.java
Extending interface set for type 'MyBrokenOption' (
OptionAspect.java) to include 'OptionAspect$IBadOptionSubtype'
(OptionAspect.java)
C:\aspectj1.5\OptionAspect.java:24 [error] IOption implementations must
provide a constructor which accepts an OptionType
class MyBrokenOption implements IXOption {
^^^^^^^^^^^^^
staticinitialization(void MyBrokenOption.<clinit>())
see also: C:\aspectj1.5\OptionAspect.java:8::0
1 error
-showWeaveInfo just shows me which is being marked as a bad option. My
correct class that implements the ctor is not flagged and my broken one
that doesn't implement it is marked with the declare error. Now I
presume I must have made some incorrect assumption in my definition of
the missing types since its working ok for me...
Andy.
