Exercise - Inspect data via context menu entry

Now it’s time to create your first full-fledged enhancement to xtUML Editor.

Task:

• Create a new context menu entry that inspects a Package and lists the Packages and Components inside it.

Jump Start:

• There are several menu-based tools already implemented in com.mentor.nucleus.bp.utilities, use them for reference.
• Copy CheckModelIntegrity.java to the Java src package com.mentor.nucleus.bp.utilities.data, then rename the file to ListPackageContents.java and let Eclipse update references.
• Open plugin.xml, find the objectContribution block for CheckModelIntegrity. Copy this block, paste it, and update the new block for the new name ListPackageContents.
• Open ListPackageContents::run(), note how it performs some actions then reports via a dialog. Replace the internals of run with your own code that selects the Package and Component children and builds a string with their names. Display the string in a dialog.
