Re: Check for serialVersionUID in Serializableclasses

Thanks for the suggestions. I spent some time today looking at both,
findbugs and javac lint checks. Either suits my needs and integrates
nicely with Hudson.

 

Thanks for the suggestions.

Given the need for deep type information, I would look at FindBug. Only
if -Xlint:serial is not enough. :-)

I don't know about #4, but doesn't -Xlint:serial do #1 - #3?

Subject: [Checkstyle-user] Check for serialVersionUID in Serializable
classes

Hi,

 

I am in need of a check that verifies that all of the classes
implementing the Serializable interface have the serialVersionUID
defined.

Trolling through the plenty available checks, I did not see such a check
being available today. I also noticed that there is a request for such
check in the bug tracking system.

If anyone has a check for this, please let me know and point me to it.

 

I have started writing my own check. The scenarios that I would need to
cover are:

1. Class implements Serializable interface, validate that
serialVersionUID is assigned

2. Class implements InterfaceA which extends Serializable, validate that
serialVersionUID is assigned

3. Class extends ClassA which implements Serializable (or Interface A),
validate that serialVersionUID is assigned.

4. Class implements Serializable through type hierarchy, but is not
serializable, i.e. throws NotSerializableException for read/writeObject,
do not require serialVersionUID.

 

Item 1 is very straight forward and I can put this together following
the "Write a Check" tutorial. I am not clear how I can establish and
examine the Type hierarchy.

 

Does anyone have suggestions as to how this Check can be implemented? Is
this something that can be accomplished using the FileSetChecks?

 

Thanks for the help,

Roman
