**Intent:** Servant is used for providing some behavior to a group of classes.
|
||
|
|
Instead of defining that behavior in each class - or when we cannot factor out
|
||
|
|
this behavior in the common parent class - it is defined once in the Servant.
|
||
|
|
|
||
|
|
|
||
|
|
|
||
|
|
**Applicability:** Use the Servant pattern when
|
||
|
|
|
||
|
|
* when we want some objects to perform a common action and don't want to define this action as a method in every class.
