public final class ComposedClosure<V> extends Closure<V>
rightShift()
and

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
