| <h2><a>Exercise 7: Extending base method content using <u>Replace</u> variability </a></h2> |
| <p>The purpose of this exercise is to extend base method content using replace variability. </p> |
| <ol> |
| <li> |
| <p>Switch to the <strong>Authoring </strong> perspective. </p> |
| </li> |
| <li> |
| <p> Create a new <strong>content package </strong> named, <span class="style1">Replace Test</span>, in the My Plugin plug-in. </p> |
| </li> |
| <li> |
| <p> Create a new <strong>role </strong>: <span class="style1">my_replace_ui_designer role</span> with presentation name, <span class="style1">My Replace UI Designer</span>. </p> |
| </li> |
| <li> |
| <p> In the <strong>Variability Type </strong> select <strong>replaces </strong> and then choose the <strong>base role </strong>: <span class="style1">rup_user_interface_designer</span>. </p> |
| </li> |
| <li> |
| <p> Add a <strong>Brief Description </strong>: <span class="style1">Replace Brief Description.</span> </p> |
| </li> |
| <li> |
| <p> Add a <strong>Main Description </strong>: <span class="style1">Replace Main Description</span>. </p> |
| </li> |
| <li> |
| <p> Save the role by closing the role editor. </p> |
| </li> |
| <li> Update the Variability Test Configuration: </li> |
| <blockquote> |
| <p> • Open the Variability Configuration and expand <strong>My Plugin > Method Content > Content Packages</strong>. </p> |
| <p>• Uncheck <strong>Extends Test</strong>. </p> |
| <p>• Check <strong>Replace Test</strong>. This is done so there are no conflicting extensions in the same method element. </p> |
| </blockquote> |
| <li> |
| <p> Switch to the <strong>Browsing </strong> perspective. </p> |
| </li> |
| <li>In the <strong>Configuration View</strong>, you will see that there is no longer a (RUP) <span class="style1">User-Interface Designer</span> role in the <strong>Role Sets </strong> folder. It was replaced by <span class="style1">My Replace UI Designer</span> role. Moreover, other content elements in the base plug-in that referenced the (RUP) <span class="style1">User-Interface Designer</span> role now reference the replacing role instead (e.g., if you open the disciplines folder and view the task <span class="style1">Design The User Interface</span> you will see that the <strong>Performing Role </strong> is now <span class="style1">My Replace UI Designer</span>.) <strong>Replace </strong> works in a similar way for <strong>tasks</strong>, <strong>artifacts </strong>, <strong>guidance </strong> and <strong>categories </strong> (feel free to try it out). </li> |
