We are migrating our application from Eclipse Indigo to Photon and I need help find a solution or alternate for a particular class which is present in Indigo but not in Photon.
The class we are trying to figure out is org.eclipse.ui.internal.navigator.AdaptabilityUtility.
Since it is an Internal class it is not available. But we had no luck finding an alternate.
Only one function of the class is used :
IAdaptable openable = (IAdaptable) AdaptabilityUtility.getAdapter(
selection.getFirstElement(), IResource.class);
If someone knows an alternative method which can be used here, it will be a great help.
Eclipse internals were completely rewritten for Eclipse 4 so in general there may not be exact alternatives for internal classes which were never part of the official API.
However for AdaptabilityUtility it looks like the current org.eclipse.core.runtime.Adapters class should work:
IResource resource = Adapters.adapt(selection.getFirstElement(), IResource.class);
Adapters.adapt uses generics so casts are not needed. Adapters is not internal so it is an official API.
