public final class CurriedClosure<V> extends Closure<V>
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"
