**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.
