Subject [jira] [Created] (OGNL-27) Move "toString" implementations into visitor pattern.
Date Sat, 15 Oct 2011 18:33:14 GMT
Move "toString" implementations into visitor pattern.
-----------------------------------------------------

                 Key: OGNL-27
                 URL: https://issues.apache.org/jira/browse/OGNL-27
             Project: OGNL
          Issue Type: New Feature
            Reporter: Daniel Pitts


Using the Visitor pattern allows for a cleaner implementation of toString().

I have a patch which will remove toString() from all AST classes, and replace it with a single
toString() in "SimpleNode" which delegates to a ToStringVisitor to build the String efficiently.
 

This patch can also be used as an example of how to move other business logic out of the AST
classes into their own visitor classes.
