Refactor toSQL method as visitor pattern
----------------------------------------
Key: CXF-3145
URL: https://issues.apache.org/jira/browse/CXF-3145
Project: CXF
Issue Type: Improvement
Components: JAX-RS
Affects Versions: 2.3.0
Reporter: Brian Topping
Priority: Minor
In doing some work with the FIQL parser, I needed to generate a different
output than SQL. By using a visitor pattern for rendering the SQL, any visitor
can be applied to the SearchCondition object graph.
The attached patch provides that refactoring.
As a part of that, SearchCondition.toSql() is deprecated, but I maintained the
interface for maximum compatibility.
There was also a change to SearchCondition.getSearchConditions(). There were
no callers to that code except test code, and it was set up to return null if
there was only one condition. That wasn't clear to me, hopefully that change
is not unreasonable.
This may not be formatted properly, please adjust to suit.
