Examples of org.dmd.dmw.DmwHierarchicObjectWrapper

org.dmd.dmw.DmwHierarchicObjectWrapper
The DmwHierarchicObjectWrapper extends the named object wrapper to indicate that the wrapped object is hierarchically named. This class also provides standardized mechanisms for arranging the objects in a traversable hierarchy i.e. so that you can easily access the named children of an object or an object's parent. This is especially handy when used in conjunction with a caching mechanism.

        indexer.deleteFromIndices(wrapper);
        
        if (name instanceof DmcHierarchicObjectName){
          DmwHierarchicObjectWrapper hwrapper = (DmwHierarchicObjectWrapper) wrapper;
          if (hwrapper.getParentComponent() != null)
            hwrapper.getParentComponent().removeSubcomponent(hwrapper);
        }
        
        wrapper.youAreDeleted();
