Execute Around idiom frees the user from certain actions that should always be executed before and after the business method. A good example of this is resource allocation and deallocation leaving the user to specify only what to do with the resource.
Use the Execute Around idiom when
- you use an API that requires methods to be called in pairs such as open/close or allocate/deallocate.
