Eclipse Plugin Developement find out which workingSet an ICompilationUnit belongs to

Question

I have an ICompilationUnit and try to find out which workingSet it belongs to , or if it even has a workingSet. I have looked at the diffrent methods that ICompilationUnit has, howeber i did not find anything that helps. Does anyone have an idea?

Answer 1

A compilation unit may be a member of 0, 1, or many working sets. You will have to search through the list of working sets seeing which contain it.

Get the working sets with:

IWorkingSetManager manager = PlatformUI.getWorkbench().getWorkingSetManager();

IWorkingSet [] sets = manager.getAllWorkingSets();

for each working set get the members with:

IAdaptable [] members = set.getElements();

Members can be many things, instanceof ICompilationUnit may work for some members or you may need to adapt:

ICompilationUnit unit = (ICompilationUnit)member.getAdapter(ICompilationUnit.class);

Note: the exact syntax of the getAdapter call varies depending on the Eclipse release as generics support was added in 4.5.
