public interface SqlNode
Represents a node in the parsed SQL statement tree structure.

SQL statements in Doma are parsed into a tree of SqlNode objects that can be traversed and processed using the visitor pattern. This interface defines the common behavior for all types of SQL nodes.

The implementation class is not required to be thread safe.

Treat this object as read-only when you cannot control its life cycle.
