[jira] [Commented] (CXF-4221) FIQL visitor to return a generic
instead of String
[ https://issues.apache.org/jira/browse/CXF-4221?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13245120#comment-13245120 ]
Sergey Beryozkin commented on CXF-4221:
---------------------------------------
> It would be great if SearchConditionVisitor<T, K> where K was the return type of the getResult() call. This way, I can CriteriaQuery<T> instead of String.
Usually the users would do SearchContext.getSearchCondition(MyClass.class) and then use the resulting search condition to select the matching MyClass instances.
The goal of SearchConditionVisitor is to accumulate a language specific (SQL, etc) representation of the FIQL query which can be fed directly to the external db/storage systems.
what introducing K to SearchConditionVisitor<T, K> help with ? Can you explain please and prototype some example code ?
> Also, incidentally, the operation isn't "getResult", it's more like "getPredicate" or "getFilter"...
Possibly not the best name, nonetheless consider it the result of the SearchConditionVisitor visiting individual SearchConsitions and transforming them all into a language specific predicate/filter
