Groovy Closure参数名称

Question

I have the following closure: def check = {x,y,z -> some code}

Is it possible to get the parameters names("x","y","z") inside the closure? and to use it as part of the closure code

For example to print arg name and then it's value.

Thanks

Answer 1

You can use of course these parameters in closure.

def a = {a, b, c ->
    a + b + c
}
assert 6 == a(1,2,3)

Second version

def a = {a, b, c ->
    [a:a, b:b, c:c]
}
assert [a:1, b:2, c:3] == a(1,2,3)
