示例1: visit
import org.codehaus.groovy.ast.CodeVisitorSupport; //导入依赖的package包/类
private static void visit(Closure closure, CodeVisitorSupport visitor) {
if (closure != null) {
ClassNode classNode = closure.getMetaClass().getClassNode();

throw new GroovyRuntimeException(
"DataSet unable to evaluate expression. AST not available for closure: " + closure.getMetaClass().getTheClass().getName() +
". Is the source code on the classpath?");
}
List methods = classNode.getDeclaredMethods("doCall");
if (!methods.isEmpty()) {
MethodNode method = (MethodNode) methods.get(0);
if (method != null) {
Statement statement = method.getCode();
