Class EMFLoadHelper

java.lang.Object

public final class EMFLoadHelper extends Object
This class provides static helper methods for accessing models during runtime. Models are stored in resources, identified by resource URIs. Concrete model elements are identified by their fragments.

  • Method Details

    • loadAndResolveEObject

      public static EObject loadAndResolveEObject(String resourceURI)
      Loads the EObject specified by the given resource URI. The resource URI has to include the concrete fragment that references the EObject; otherwise an EObject cannot be uniquely identified in a given resource. For example, the String "platform:/resource/myProject/default.usagemodel#_ieXlgKDrEeKjDcfkNgs1Gg" correctly includes a fragment while "platform:/resource/myProject/default.usagemodel" does not. Use the getResourceURI(...) method of this class in case you want to get a correct resource URI for a given EObject.
      Parameters:
      resourceURI - Resource URI to a given EObject (has to include fragment).
      Returns:
      The referenced EObject.

    • getResourceURI

      public static String getResourceURI(EObject eObject)

      Parameters:
      eObject - The given EObject.
      Returns:
      The URI String of the given object; including its fragment.

    • getResourceFragment

      public static String getResourceFragment(EObject eObject)
      Returns the URI fragment of a given eObject.
      Parameters:
      eObject - the eObject to look the fragment up for.
      Returns:
      the fragment of the eObject.
