public <A extends Appendable> A appendTo(A appendable,
                                         Map<?,?> map)
                              throws IOException

IOException

public StringBuilder appendTo(StringBuilder builder,
                              Map<?,?> map)

public Joiner.MapJoiner useForNull(String nullText)
