One obvious approach to reducing the complexity of implementing the multi-layered component hierarchies we described in the previous chapter is to restrict possible interaction directions. As we described in the “Weak Coupling” chapter, we could simplify the implementation if we allow subcomponents to call the parent context's methods directly.
