## [Java] Class CurriedClosure<V>

- org.codehaus.groovy.runtime.CurriedClosure

- 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

- - ### Constructor Detail

    - #### public CurriedClosure(int index, Closure<V> uncurriedClosure, Object... arguments)

      Creates the curried closure.

      Parameters:
        `index` - the position where the parameters should be injected (-ve for lazy)
        `uncurriedClosure` - the closure to be called after the curried parameters are injected
        `arguments` - the supplied parameters

    - #### public CurriedClosure(Closure<V> uncurriedClosure, Object... arguments)

  - ### Method Detail

    - #### @SuppressWarnings("unchecked") public Object clone()

    - #### public Object getDelegate()

    - #### public Class[] getParameterTypes()

    - #### public int getResolveStrategy()

    - #### public Object[] getUncurriedArguments(Object... arguments)

    - #### public void setDelegate(Object delegate)

    - #### public void setResolveStrategy(int resolveStrategy)
