An initial filter is defined in order to show only those projects that have a UNICOM® Digital Transformation Toolkit (UDTT™) nature. This filter is defined as a common filter for the navigator content:
The class implementing this filter is com.ibm.btt.tools.projectexplorer.BetaDevExplorerFilter.
All other filters applied to the model in order to be shown in the Beta Developer Explorer view are done inside the content provider code, com.ibm.btt.tools.transaction.perspective.wizards.PerspectiveContentProvider.
