RE: [aspectj-dev] static inter-type field on interface not suppor ted

[Rice Yeh <riceyeh@xxxxxxxxx>]

Hi Jim,
  I think I can NOT answer you if this limitation
cause me major annoynance but let you know my design
and the thinking behind it.
  First, of course I will intuitively use static field
in interface since static field is allowed in
Interface in Java language. Conversely, instance
fields are allowed in interface surprised me a little.
  Second, I use AspectJ to support my design for
dynamic properties added to objects of a class. Since
dynamic properties are added to objects at run time
v.s fixed properties are defined at class level at
compiling time, I need a static field called
'all_dynamic_properties' to manage those dynamic
proerties added to any object in the class. For any
dynamic property value getting, I go to this field to
check if this property was added to other objects
before for an object without this dynamic property
added. If it is, a null value is returned, otherwise a
property_not_defined_exception is thrown. 
With this limition, I can have this design. Will it
cause me anonynance? Staying at AspectJ 1.0.6 will
solve my problem since I do not use any new feature in
1.1 version. When I start to using features in 1.1, it
does cause me big anonynance.

Regards,
Rice
