public final class LegacyResourceSupport extends Object
Provides access to resource-specific classes, needed to provide backwards compatibility for resource-specific functions which could not be moved up from the generic workbench layer to the IDE layer.

    • adaptSelection

      public static IStructuredSelection adaptSelection(IStructuredSelection selection, String objectClass)
      Adapts a selection to the given objectClass considering the Legacy resource support. Non resource objectClasses are adapted using the IAdapterManager and this may load the plug-in that contributes the adapter factory.

      The returned selection will only contain elements successfully adapted.

      Parameters:
      selection - the selection to adapt
      objectClass - the class name to adapt the selection to
      Returns:
      an adapted selection
      Since:
      3.1

    • getAdapter

      public static Object getAdapter(Object element, String objectClass)
      Adapts an object to a specified objectClass considering the Legacy resource support. Non resource objectClasses are adapted using the IAdapterManager and this may load the plug-in that contributes the adapter factory.

      The returned selection will be of the same size as the original, and elements that could not be adapted are added to the returned selection as is.

      Parameters:
      element - the element to adapt
      objectClass - the class name to adapt the selection to
      Returns:
      an adapted element or null if the element could not be adapted.
      Since:
      3.1

    • getAdaptedResource

      public static Object getAdaptedResource(Object element)
      Adapt the given element to an IResource using the following search order:
      1. using the IContributorResourceAdapter registered for the given element, or
      2. directly asking the element if it adapts.
      Parameters:
      element - the element to adapt
      Returns:
      an IResource instance if the element could be adapted or null otherwise.
      Since:
      3.1

    • getAdaptedResourceMapping

      public static Object getAdaptedResourceMapping(Object element)
      Adapt the given element to an ResourceMapping using the following search order:
      1. using the IContributorResourceAdapter2 registered for the given element, or
      2. directly asking the element if it adapts.
      Parameters:
      element - the element to adapt
      Returns:
      an ResourceMapping instance if the element could be adapted or null otherwise.
      Since:
