  org.eclipse.emf.compare.ui.viewer.content.part.ModelContentMergeTabItem

public final class ModelContentMergeTabItem
extends java.lang.Object

This class will be used to wrap Item subclasses such as TreeItem and TableItem to allow us to call methods such as getBounds without explicitely casting each time we do so.

This wrapper will allow us to maintain a logical structure of the tree : which TreeItem corresponds to which difference or visible parent ...
