A caller MUST call one of the <code>source</code> methods - * (e.g. {@link #source(IRI)}, {@link #source(Path)}, - * {@link #source(InputStream)}), and MUST call one of the <code>target</code> - * methods (e.g. {@link #target(Consumer)}, {@link #target(Dataset)}, - * {@link #target(Graph)}) before calling {@link #parse()} on the returned - * RDFParser - however methods can be called in any order. - * <p> - * The call to {@link #parse()} returns a {@link Future}, allowing asynchronous - * parse operations. Callers are recommended to check {@link Future#get()} to - * ensure parsing completed successfully, or catch exceptions thrown during - * parsing. - * <p> - * Setting a method that has already been set will override any existing value - * in the returned builder - regardless of the parameter type (e.g. - * {@link #source(IRI)} will override a previous {@link #source(Path)}. Settings - * can be unset by passing <code>null</code> - note that this may require - * casting, e.g. <code>contentType( (RDFSyntax) null )</code> to undo a previous - * call to {@link #contentType(RDFSyntax)}. - * <p> - * It is undefined if a RDFParser is mutable or thread-safe, so callers should - * always use the returned modified RDFParser from the builder methods. The - * builder may return itself after modification, or a cloned builder with the - * modified settings applied.
