Direct Known Subclasses:

FirstParam.Component

public class FirstParam
extends PickAnyArgumentHint

A hint used to instruct the type checker to pick the first parameter type. For example:

public <T> def doWith(T src, @ClosureParams(FirstParam.class) Closure c) { c.call(src); }

This class has several inner classes that also helps picking generic argument types instead of the parameter type.
