Correct patterns. Factories
How can i implement this? or perhaps it is correct.
My case is the following one:
-I磛e got an object called "series" that represents a sequence of objects. For instance: BrushYellowSerie(set of yllow brushes), BrushRedSerie.
- I磛e got an object called "reports" that represents reports about the series. There are different kind of reports. A report can hace one serie, or two or free series or other objects regarding a external variable(called experienceType).
- I have thougth in creating a ReportManagerFactory. That allows me to choose the ReportManager depending the experience.
- There would be different kinds of ReportManager, one for report. For example ReportY, ReportAManager, ReportM.
- Each ReportManager must implement a function called "getAllReports". That will get all reports from a Experience. That is, if i 磛e got experience 7 that is of type 9 I磛e got 7 ReportJ.
- "ReportAManager.getAllReports" will return an ArrayLIst of "reports".
The problem is: I磛e got thought in creating a class called "Report" with two attributes: Id and String. Later I would like to have a descendant class for each reportType (that is ReportA, ReportB, ReportC).
ReportA is the same that a Serie, and ReportAManager.getAllReports will return an ArrayList of ReportA. I 磛e got thought in calling directly a function that I磛e got that returns all the series. But this function return series
that is not a Report. Ive got thought that ReportA descend from Report and Serie. How can i pass the "array of Series" to an "array of ReportA". How can i do that?

OK. Why? The color of the brush would seem to be merely an atribute of the brush. Do yellow brushes have a different behavior than red brushes?

Why? If you don't need to create new types, you are usually better off not doing so. You can create new implementation classes but creating a bazillion global types in the system is definitely not good OO design.
