Construct a new stream object writing the data to a string.

If the provided pointer is non-@NULL, data will be written to it.

Otherwise, an internal string is used for the data written to this

stream, use GetString() to get access to it.

If @a str is used, data written to the stream is appended to the current
|
|
contents of it, i.e. the string is not cleared here. However if it is not
|
|
empty, the positions returned by wxOutputStream::TellO will be
|
|
offset by the initial string length, i.e. initial stream position will be the
|
|
initial length of the string and not 0.
|
|
|
|
Notice that the life time of @a conv must be greater than the life time
|
|
of this object itself as it stores a reference to it. Also notice that
|
|
with default value of this argument the data written to the stream must
|
|
be valid UTF-8, pass @c wxConvISO8859_1 to deal with arbitrary 8 bit
|
|
data.
