Groovy: Closure Composition
Closure composition corresponds to the concept of function composition, that is to say creating a new function by composing two or more functions (chaining calls), as illustrated in this example:
def plus2 = { it + 2 } def times3 = { it * 3 } def times3plus2 = plus2 << times3 assert times3plus2(3) == 11 assert times3plus2(4) == plus2(times3(4)) def plus2times3 = times3 << plus2 assert plus2times3(3) == 15 assert plus2times3(5) == times3(plus2(5)) // reverse composition assert times3plus2(3) == (times3 >> plus2)(3)
