Corresponds to a bag. One level of abstraction higher than factory pattern – It is a factory method that returns one of several factories Express it with real world examples. Additionally, some algorithms might be tailored for a specific application, so including them into a generic collection class would be weird. Your code gets focused on implementation details, rather than coding at level that’s closer to the problem domain. The collection provides several iterators that can traverse profiles in various ways. If you're a programmer or architect who wants the clearest possible understanding of design patterns–or if you've struggled to make them work for you–read this book. It’s a pretty simple pattern once you break it down. This itinerary will hit all the highlights and is considered the Best of Slovenia with a cultural twist. Use the Iterator pattern when your collection has a complex data structure under the hood, but you want to hide its complexity from clients (either for convenience or security reasons). 225 clear and helpful illustrations and diagrams. SUMMARY There are many benefits to using the Standard Template Library (STL) for C++ … At the very least, it must have a method for fetching the next element from a collection. Since its inception, the concept of design pattern has been around in the programming world. patterns, section 6 describing the advantages and disadvantages of design patterns in 7, section 8 concluding the paper.

If you need a special way to traverse a collection, you just create a new iterator class, without having to change the collection or the client. An iterator is an abstraction over how a collection is implemented. It lets you go over the whole collection one item at a time, optionally removing items. The disadvantage of an Iterator is that it can be a lot slow if you DO know the underlying implementation. Go over the client code to replace all of the collection traversal code with the use of iterators.
