RE: [birt-dev] Java Event Handlers

By extending the adapters, we guarantee that if we change the
interfaces, the user's script code will still compile (although it might
not be executed). So I guess it's up to the user to decide if they
prefer compile errors or not if the interfaces are updated. This should
probably be documented somewhere.

Subject: [birt-dev] Java Event Handlers

This is probably for Petter,

I noticed in the documentation where they show Java event handlers, they

demonstrate creating handler classes by implementing items from the 
org.eclipse.birt.report.engine.api.script.eventhandler package.  I see 
that for each of the interfaces, a default implementation has all ready 
been created in org.eclipse.birt.report.engine.api.script.eventadapter. 

Is it preferable to have people implement the interface or just have 
them extend the eventadapter classes?

If extending eventadapter is preferable I will create a Bugzilla entry.
