## [Java] Class ComposedClosure<V>

- org.codehaus.groovy.runtime.ComposedClosure

-     public final class ComposedClosure<V>
      extends Closure

  A wrapper for Closure to support composition. Normally used only internally through the `rightShift()` and `leftShift()` methods on `Closure`.

  Typical usages:

       def twice = { a -> a * 2 }
       def inc = { b -> b + 1 }
       def f = { x -> twice(inc(x)) } // longhand
       def g = inc >> twice
       def h = twice << inc
       assert f(10) == 22
       assert g(10) == 22
       assert h(10) == 22

       def s2c = { it.chars[0] }
       def p = Integer.&toHexString >> s2c >> Character.&toUpperCase
       assert p(15) == 'F'

       def multiply = { a, b -> a * b }
       def identity = { a -> [a, a] }
       def sq = identity >> multiply
       assert (1..5).collect{ sq(it) } == [1, 4, 9, 16, 25]

       def add3 = { a, b, c -> a + b + c }
       def add2plus10 = add3.curry(10)
       def multBoth = { a, b, c -> [a*c, b*c] }
       def twiceBoth = multBoth.rcurry(2)
       def twiceBothPlus10 = twiceBoth >> add2plus10
       assert twiceBothPlus10(5, 10) == 40
