groovy.lang.Closure<V>
org.codehaus.groovy.runtime.CurriedClosure<V>
- All Implemented Interfaces:
GroovyCallable<V>
,GroovyObject
,Serializable
,Cloneable
,Runnable
,Callable<V>
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"
