Use values stored in a string as Enum Object?

I have an enum. And a string contains the name of the enum. I want to access the enum using the string. Something like this. But this does not work :(

public enum Level {     HIGH,     MEDIUM,     LOW }
def x = "Level"
println "$x".values();

You have to do it like this: 

public enum Level {     HIGH,     MEDIUM,     LOW }
def x = this.class.classLoader.loadClass('Level', true)
println x.values()

Here's an alternative way:

public enum Level {     HIGH,     MEDIUM,     LOW }
def x = "Level"
println Eval.me("${x}").values()

You can do it using Class.forName method. For example

    public enum Level {     
        HIGH,     
        MEDIUM,     
        LOW 
    }

    def clazz = Class.forName("Level")
    println clazz.values()

Remember you should use FULLY QUALIFIED CLASSNAME. For more details http://docs.oracle.com/javase/7/docs/api/java/lang/Class.html#forName(java.lang.String)
