Use exception handling pattern in visitors
------------------------------------------
Key: QI-264
URL: http://issues.ops4j.org/browse/QI-264
Project: Qi4j
Issue Type: Improvement
Affects Versions: 1.1
Reporter: Rickard Öberg
Assignee: Rickard Öberg
Fix For: 1.2
Stanislav suggested that we use an exception handling pattern in our visitors.
Basically the visitor interface/method is declared with "ThrowableType extends
Exception". If the visitor needs to throw a particular type of exception, like
SQLException, then that is specified during instantiation. If not, then
RuntimeException can be used. This provides a natural way to "cancel" a
visitation.
