[Java] Class CurriedClosure

java.lang.Object
  groovy.lang.GroovyObjectSupport
      groovy.lang.Closure
          org.codehaus.groovy.runtime.CurriedClosure

public final class CurriedClosure
extends Closure

A wrapper for Closure to support currying. Normally used only internally through the curry(), rcurry() or ncurry() methods on Closure. Typical usages: 

 // normal usage
 def unitAdder = { first, second, unit -> "${first + second} $unit" }
 assert unitAdder(10, 15, "minutes") == "25 minutes"
 assert unitAdder.curry(60)(15, "minutes") == "75 minutes"
 def minuteAdder = unitAdder.rcurry("minutes")
 assert minuteAdder(15, 60) == "75 minutes"

 // explicit creation
 import org.codehaus.groovy.runtime.CurriedClosure
 assert new CurriedClosure(unitAdder, 45)(15, "minutes") == "60 minutes"
 assert new CurriedClosure(unitAdder, "six", "ty")("minutes") == "sixty minutes"
