public interface GroovyCodeVisitorDefines the visitor interface for traversing and processing Groovy AST nodes using the visitor pattern. Implementations can perform compilation, transformation, code generation, or analysis by implementing visit methods for specific statement and expression types. The interface provides both required abstract methods and default convenience methods for handling generic collections and null values.
