/**
|
|
* Step Builder Pattern
|
|
*
|
|
* <p><b>Intent</b> <br>
|
|
* An extension of the Builder pattern that fully guides the user through the creation of the object
|
|
* with no chances of confusion. <br> The user experience will be much more improved by the fact
|
|
* that he will only see the next step methods available, NO build method until is the right time to
|
|
* build the object.
|
|
*
|
|
* <p><b>Implementation</b> <br>
|
|
* The concept is simple:
|
|
* <ul>
|
|
*
|
|
* <li>Write creational steps inner classes or interfaces where each method knows what can be
|
|
* displayed next.</li>
|
|
*
|
|
* <li>Implement all your steps interfaces in an inner static class.</li>
|
|
*
|
|
* <li>Last step is the BuildStep, in charge of creating the object you need to build.</li>
|
|
* </ul>
|
|
*
|
|
* <p><b>Applicability</b> <br>
|
|
* Use the Step Builder pattern when the algorithm for creating a complex object should be
|
|
* independent of the parts that make up the object and how they're assembled the construction
|
|
* process must allow different representations for the object that's constructed when in the
|
|
* process of constructing the order is important.
|
