readObject

private void readObject(ObjectInputStream s)
                 throws IOException,
                        ClassNotFoundException

Reads a mutable string in serialised form.

Mutable strings produced by this method are always compact; this seems reasonable, as stored strings are unlikely going to be changed.

Because of limitations of ObjectInputStream, this method must read one character at a time, and does not try to do any read-ahead (in particular, it does not create any object). On non-buffered data inputs it might be very slow.

Throws:

IOException

ClassNotFoundException

writeObject

private void writeObject(ObjectOutputStream s)
                  throws IOException

Writes a mutable string in serialised form.

The serialised version of a mutable string is made of its length followed by its characters (in UTF-16 format). Note that the compactness state is forgotten.

Because of limitations of ObjectOutputStream, this method must write one character at a time, and does not try to do any caching (in particular, it does not create any object). On non-buffered data outputs it might be very slow.
