Subject [jira] Created: (DERBY-673) Get rid of the NodeFactory
Date Wed, 02 Nov 2005 17:21:56 GMT
Get rid of the NodeFactory

         Key: DERBY-673
         URL: http://issues.apache.org/jira/browse/DERBY-673
     Project: Derby
        Type: New Feature
    Reporter: Rick Hillegas

This piece of code once had a purpose in life. It was one of the double-joints which allowed
cloudscape to ship with and without compiler support for the synchronization language. Synchronization
has been removed. If we want to plug in optional language components, I think there are better
ways to do this.

The NodeFactory turned into a big, sprawling piece of code. At some point this code was slimmed
down by telescoping all of its factory methods into a couple unwieldly, weakly-typed overloads
backed by cumbersome logic in the actual node constructors. I would like to reintroduce strongly
typed node constructors which the parser can call directly. This will make node generation
easier to read and less brittle and it will get rid of the now useless NodeFactory class.
