Is there any way to create a chain of method references like;

Chain chain = Product::getType::getTypeInfo::getTypeInfoId;

I want to create a generic null check method.

public Optional checkIfNull(Object object, Chain chain){
    return Optional.ofNullable(object).map(chain).isPresent();
}

use a lambda? `product -> product.getType().getTypeInfo().getTypeInfoId()` – Jorn Vernee Mar 20 '18 at 12:17
