const fxl::WeakPtr< ::a11y::SemanticTree> Get ()

Returns a weak pointer to the Semantic Tree owned by this service. Caller

must always check if the pointer is valid before accessing, as the pointer

may be invalidated. The pointer may become invalidated if the semantic

provider disconnects or if an error occurred. This is not thread safe. This

pointer may only be used in the same thread as this service is running.
