  • Field Details

    • EDITOR_KEY

      public static final QualifiedName EDITOR_KEY
      The persistent property key used on IFile resources to contain the preferred editor ID to use.

      Example of retrieving the persisted editor id: 

       
  IFile file = ...
  IEditorDescriptor editorDesc = null;
  try {
        String editorID = file.getPersistentProperty(EDITOR_KEY);
        if (editorID != null) {
                editorDesc = editorReg.findEditor(editorID);
        }
  } catch (CoreException e) {
        // handle problem accessing persistent property here
  }

      Example of persisting the editor id: 

       
  IFile file = ...
  try {
        file.setPersistentProperty(EDITOR_KEY, editorDesc.getId());
  } catch (CoreException e) {
        // handle problem setting persistent property here
  }

    • EDITOR_ID_ATTR

      public static final String EDITOR_ID_ATTR
      An optional attribute within a workspace marker (IMarker) which identifies the preferred editor type to be opened.
      See Also:

    • RESOURCE_PERSPECTIVE_ID

      public static final String RESOURCE_PERSPECTIVE_ID
      The resource based perspective identifier.
