Intent: 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.

Applicability: 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.
