Enclosing class:

SecondParam

public static class SecondParam.Component
extends SecondParam

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

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