[JIRA] Created: (CAY-942) Generic types
Generic types
-------------
Key: CAY-942
URL: https://issues.apache.org/cayenne/browse/CAY-942
Project: Cayenne
Issue Type: Improvement
Reporter: Scott Anderson
Assignee: Andrus Adamchik
Priority: Minor
I realize that this would restrict functionality to Java 5+, but I still believe it would be a good option to have for the code generator in the modeler:
Add, as an option, generic types to Lists in generated classes. It's quite annoying to have to cast types; much of my code looks like this:
for(Object o : someObject.getSomeManyToManyField()) {
TheTypeIWanted ttiw = (TheTypeIWanted) o;
...
}
With generics, it would be:
for(TheTypeIWanted ttiw : someObject.getSomeManyToManyField()) {
...
}
It'd also be nice if the core libraries had generics. For example, "Object DataObjectUtils.objectForPk(Class, int)" could be changed to "T DataObjectUtils.objectForPk(Class<T>, int)" to avoid casting.

[JIRA] Closed: (CAY-942) Generic types

Ari Maniatis closed CAY-942.
----------------------------
Resolution: Fixed
Fix Version/s: 3.0
Assignee: Ari Maniatis (was: Andrus Adamchik)
Generics have already been implemented in trunk and many will be available in 3.0M3. This is ongoing work and more needs to be done over time, but a large part of this is complete.

----------------------------------
Yes, it will be done, but the best way forward isn't 100% clear yet. See this for discussion:

------------------------------------
Awesome; I've built the library from SVN, and have fell in love with it - great work!
Are there any plans to add generics to the Query objects?

------------------------------------
This would also have the advantage of restricting the class passed to objectForPk to a Class<? extends CayenneDataObject>
public static <T extends CayenneDataObject> T objectForPk(Class<T> type, int pk);
