    • getObjectName

      public String getObjectName(Object obj)
      Description copied from interface: IEmfService
      Returns the human readable name of a given object or the EMF id if no name can be found. The method tries to access a modeled attribute "name" or "id" in this order. If no attribute with this name is modeled, the first attribute whose value is a String or TranslatableTextFragment is returned, otherwise null .
      Specified by:
      getObjectName in interface IEmfService
      Parameters:
      obj - the object to get a name for
      Returns:
      the value of attribute "name" or the EMF id if no attribute "name" exists

    • getEObject

      public org.eclipse.emf.ecore.EObject getEObject(Object object)
      Description copied from interface: IEmfService
      Tries to convert the given object to a EObject
      • using #adaptObject(Object, Class),
      • unwrapping an IStructuredSelection.
      Specified by:
      getEObject in interface IEmfService
      Parameters:
      object - the object to convert
      Returns:
      the target object or null
      See Also:

    • getFile

      public org.eclipse.core.resources.IFile getFile(org.eclipse.emf.ecore.EObject object)
      Description copied from interface: IEmfService
      Returns the Eclipse file for the given EObject's Resource . Note that the file is null for objects in
      • archives,
      • closed projects,
      • not yet persisted resources or not yet persisted EObjects in already persisted resources. In this respect this methods behaves asymmetric to the handle-only resource APIs like IProject.getFile(String).
      Specified by:
      getFile in interface IEmfService
      Parameters:
      object - the model object to get the file for
      Returns:
      the partition file or null under the mentioned circumstances
      See Also:

    • getFile

      public org.eclipse.core.resources.IFile getFile(org.eclipse.emf.common.util.URI uri)
      Description copied from interface: IEmfService
      Returns the Eclipse file for the given URI. Note that the file is null for objects in
      • archives,
      • closed projects,
      • not yet persisted resources or not yet persisted EObjects in already persisted resources. In this respect this methods behaves asymmetric to the handle-only resource APIs like IProject.getFile(String).
      Specified by:
      getFile in interface IEmfService
      Parameters:
      uri - the URI to get the file for
      Returns:
      the file or null under the mentioned circumstances
      See Also:

    • getFileForUriString

      protected org.eclipse.core.resources.IFile getFileForUriString(String uriString)

    • toString

      public StringBuilder toString(org.eclipse.emf.ecore.EObject o, StringBuilder result)
      Description copied from interface: IEmfService
      Creates an extended string presentation of the given EObject, including its type and attributes
      Specified by:
      toString in interface IEmfService
      Parameters:
      o - the object to create a string presentation for
      result - the string buffer to store the result into
      Returns:
      the same string buffer as result per convenience
      See Also:
      • #toString(EObject)

      Specified by:
      getFileURI in interface IEmfService
      Parameters:
      file - The file to construct the URI for
      Returns:
      The platform resource URI for the given file.

    • mapDiagramFileUriToDiagramUri

      public org.eclipse.emf.common.util.URI mapDiagramFileUriToDiagramUri(org.eclipse.emf.common.util.URI diagramFileUri)
      Description copied from interface: IEmfService
      Maps the fileURI to an URI which points directly to the Diagram Object. This methods assumes the Diagram object is the first root object in the given file.
