For a recent class project we were required to modify code within an existing class method in a MIPS simulator. I completed the assignment successfully but it has bothered me that I really didn't have to understand the method definition.

There's a lot going there. Can you help break it down for me?

I think you mean that you would like help to understand the method declaration, not the method definition. The definition is everything in between . Am I correct?

This is the definition of the findLine2Replace method for the template class CacheAssoc (including everything within the braces which you have omitted).
template<class State, class Addr_t, bool Energy>
These are the template parameters, the first two are type template parameters and the final one is a boolean parameter (can only be true or false). This should be the same as it appears for the class definition.
typename CacheAssoc<State, Addr_t, Energy>::Line*
This is the function return type. The typename keyword is necessary as CacheAssoc is a dependent type, it relies on unknown template parameters. ::Line must be a type that is defined within the CacheAssoc class.
CacheAssoc<State, Addr_t, Energy>::findLine2Replace(Addr_t addr, bool ignoreLocked)
Is the function name and argument list. If you were to define this method within the scope of the CacheAssoc class, the following would not be necessary CacheAssoc<State, Addr_t, Energy>::, however as this is not the case, it is necessary.
