java.lang.Object groovy.util.Eval
public class Eval extends Object
Allow easy integration from Groovy into Java through convenience methods.
This class is a simple helper on top of GroovyShell. You can use it to evaluate small Groovy scripts that don't need large Binding objects. For example, this script executes with no errors:
assert 10 == Eval.me(' 2 * 4 + 2') assert 10 == Eval.x(2, ' x * 4 + 2')
