• getRootResource

  CDOResource getRootResource()

  Returns the root resource of the repository.

  The root resource is a special resource with only CDOResourceNodes in its contents list. You can use it as the main entry into the new resource and folder structure.

• setResourcePathCache

  void setResourcePathCache(Map<String,CDOID> resourcePathCache)

  Sets the new map to be used as a cache for various get*Resource*(String path) methods.

  Can be used to reset/clear the resource path cache by passing a new HashMap<String, CDOID>(). Smarter maps could implement a LRU eviction policy to limit the map capacity. Passing null disables resource path caching.

  The default value is new HashMap<String, CDOID>().
