Returns the charset this encodes its output in

write

public GenericWriter write(AbstractUtf8Array v)
                    throws IOException

Overrides:

write in class GenericWriter

Throws:

IOException

write

appended

public long appended()

Return the number of bytes this writer will produce for the underlying layer. That is, it sums the length of the raw bytes received and the number of bytes in the written strings after encoding.

Returns:

the number of bytes appended to this writer
