EMF Compare/API GetVisibleDiffElements
The API enables to get visible differences from a CompareEditor or its input. It is the service class: ModelStructureMergeViewerService which contains this API:
List<DiffElement> getVisibleDiffElements(CompareEditor compareEditor)
There are different declensions, in relation to the available inputs:
List<DiffElement> getvisibleDiffElements(ICompareInput input, Composite parent, CompareConfiguration configuration)
List<DiffElement> getVisibleDiffElements(final CompareConfiguration compareConfiguration, final ICompareNavigator compareNavigator)
There is an other API to retrieve the visible differences ordered by the configured grouping, with the same declensions:
Map<UIDifferenceGroup, List<DiffElement>> getGroupedDiffElements(CompareEditor compareEditor)
Map<UIDifferenceGroup, List<DiffElement>> getGroupedDiffElements(ICompareInput input, Composite parent, CompareConfiguration configuration)
Map<UIDifferenceGroup, List<DiffElement>> getGroupedDiffElements(final CompareConfiguration compareConfiguration, final ICompareNavigator compareNavigator)
