org.codehaus.groovy.transform.tailrec.ReturnAdderForClosures

All Implemented Interfaces:

GroovyCodeVisitor

public class ReturnAdderForClosures
extends CodeVisitorSupport

Adds explicit return statements to implicit return points in a closure. This is necessary since tail-recursion is detected by having the recursive call within the return statement.
