How and why routers bind subnet mask to updates received

Dear friends

Can someone explains how routers bind subnet mask to routing updates received from other routers when they themselves have some interface of that class itself and what are the different cases and treatment.

Like

1. when routers dont have entries of that class of network

2. when routers have interface configured for that class and the same class of routing update is coming from other neighboring routers

3. if they have more than one class of subnet assign to its interface but different subnet mask and when they receives update from other neighboring routers what are the actions they take.

I am taking the case with Classful routing protocols

Please explain point by point if possible with example also
