CurriedClosure (Groovy 4.0.0)

org.codehaus.groovy.runtime.CurriedClosure

public final class CurriedClosure<V>
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"

Notes:

Caters for Groovy's lazy (rcurry) and eager (ncurry) calculation of argument position
