Enclosing class:

FirstParam

public static class FirstParam.Component
extends FirstParam

A hint used to instruct the type checker to pick the type of the component of the first parameter type, which is therefore expected to be an array, like in this example:

void <T> doWithArray(T[] array, @ClosureParams(FirstParam.Component.class) Closure c) { array.each { c.call(it)} }
