Interface SqlNodeVisitor<R>

Type Parameters:

R - node being visited

public interface SqlNodeVisitor<R>

Implementation of the Visitor pattern for the SqlNode. Benefit of this Visitor implementation: We get compile time safety that all Visitors have implementations for all SqlNode types. Drawback of this Visitor implementation: Whenever a new SqlNode gets added, we need to implement it here (should be fine for now). If this becomes to annoying, we can still switch to a visitor pattern using Reflection.
