      <T extends DataObject> @NonNull DescendantQueryBuilder<T> querySubtree(InstanceIdentifier<T> rootPath)
      Create a new DescendantQueryBuilder for a specified root path. Root path must be a non-wildcard InstanceIdentifier in general sense. If the target type represents a list, the last path argument may be a wildcard, in which case the path is interpreted to search the specified list. Inner path elements have to be always non-wildcarded.
      Type Parameters:
      T - Target object type
      Parameters:
      rootPath - Subtree root
      Returns:
      a subtree query instance
      Throws:
      IllegalArgumentException - if rootPath is incorrect
      NullPointerException - if rootPath is null
