[aspectj-users] Implementation of party and partyroles

["Vankeirsbilck, Rudi. (BE - Merelbeke)" <ruvankeirsbilck@xxxxxx>]

Hi all,

Consider the party analysis design pattern and link that with the role
analysis design pattern.

You can imagine the abstract class Party with two concrete subclasses:
Person and Company.
You can also image the abstract class PartyRole with two abstract
subclasses PersonRole and CompanyRole, both having (as an example) the
following respective concrete subclasses:

PersonRole: Employee, Customer
CompanyRole: Employer, Manufacturer, Carrier, Insurer

So far, I have only seen compile time implementations of aspects, i.e.
the code is weaved into the .class files and every instances has or
doesn't have the aspect code.
Is this a limitation of AspectJ or is it possible to implement the role
classes with aspects and assign the aspects at runtime on an instance
basis? How would you do that with AspectJ?

Many thanks,

Rudi.
