[news.eclipse.modeling.gmf] Re: Sort/Filter Compartment Items...

["Thomas Beyer" <thomas.beyer@xxxxxxxxxxxxxxxxxxxx>]

Hello Tatiana,

thank you very much for your detailed information.
My focus was targeted more against the sort functionality.
I am trying to implement some native functionality like in ms excel -> right 
click -> sort by -> select a column (resp. an attribute) and gmf is doing 
the rest. The result shoul be, that the notation as well as the domain model 
lists are updated accordingly. I am trying to use this for 
listcompartmenteditparts.
Haven't been successfull so far.
Do you also haven some suggestions to achieve this?

TIA & Regards
Thomas

Hi Thomas,

The functionality works properly, though it could be documented better. It's 
used in UML2 Tools in order to implement DetailLevels 
(http://wiki.eclipse.org/index.php/MDT_1.0_New_and_Noteworthy#Detail_Levels).

How elements are filtered from compartment is defined in 
XXXCompartmentEditPart#getChildrenFilteredBy(List filterKeys). The method 
returns list of elements that will be hidden for a given filterKey.
The filter key should be set to a Node. UML2 Tools add filterKey using the 
following Command:

FilteringStyle style = (FilteringStyle) 
view.getStyle(NotationPackage.eINSTANCE.getFilteringStyle());
List<EditElementCommand> result = new ArrayList<EditElementCommand>(2);

SetRequest setFilteringRequest = new SetRequest(editingDomain, style, 
NotationPackage.eINSTANCE.getFilteringStyle_Filtering(), 
Filtering.AUTOMATIC_LITERAL);
result.add(new SetValueCommand(setFilteringRequest));

List<String> filteringKeys = new ArrayList<String>(1);
filteringKeys.add(UMLDetailLevelService.FILTER_BY_VISIBILITY);
SetRequest setKeysRequest = new SetRequest(editingDomain, style, 
NotationPackage.eINSTANCE.getFilteringStyle_FilteringKeys(), filteringKeys);
result.add(new SetValueCommand(setKeysRequest));

Thomas, you can find more implementation details in 
org.eclipse.uml2.diagram.clazz.details.AnalysisLevel class.  I've attached a 
PSF file referencing the project containing the class.

Best wishes,
Tanya.
