Detailed Description

A BasicComponentParameter should be used to pass in a particular component as argument to a different component's constructor. This is particularly useful in cases where several components of the same type have been registered, but with a different key. Passing a ComponentParameter as a parameter when registering a component will give PicoContainer a hint about what other component to use in the constructor. This Parameter will never resolve against a collecting type, that is not directly registered in the PicoContainer itself.
