#include <rw/stream/RWUCharToUTF8ByteOutputStreamImp.h>

Concrete class connecting a UTF-16 character stream to aUTF-8 binary stream. The UTF-16 characters are transformed as a sequence of UTF-8 bytes. UTF-8 is a variable length encoding of the Unicode Standard using 8-bit sequences, where the high bits indicate which part of the sequence a byte belongs to. Implements the body idiom from the handle-body pattern.

RWUCharToUTF8ByteOutputStreamImp(RWByteOutputStream&
                                 sinkStream);

Initializes the reference to the binary stream that will be used as the sink of bytes.

Parameter List

sinkStream

The binary stream that will serve as the sink of bytes.

virtual 
~RWUCharToUTF8ByteOutputStreamImp();

Destructor.

static RWUCharOutputStream 
make(RWByteOutputStream& sink);

Constructs an RWUCharToUTF8ByteOutputStreamImp instance that uses sink as its sink of bytes, and returns a handle to it. Throws no exceptions.

Parameter List

sink	The binary stream that is used as the sink of bytes.

virtual void 
close();

This function is forwarded to the binary stream used as the sink of bytes.

virtual void 
flush();

This function is forwarded to the binary stream used as the sink of bytes.

virtual bool 
isBad() const;

This function is forwarded to the binary stream used as the sink of bytes. Throws no exceptions.

virtual bool 
isFail() const;

This function is forwarded to the binary stream used as the sink of bytes. Throws no exceptions.

virtual bool 
isGood() const;

This function is forwarded to the binary stream used as the sink of bytes. Throws no exceptions.

virtual void 
write(RWUChar unicodeValue);

Encodes, and writes a single UTF-16 character to the binary stream used as the sink of bytes.

Parameter List

unicodeValue

The UTF-16 character to be encoded.

virtual void 
write(const RWUChar* unicodeArray, RWSize numUChars);

Encodes, and writes an array of UTF-16 characters to the stream used as the sink of bytes.

Parameter List

unicodeArray	A pointer to the first element of the array.
numUChars	The number of UTF-16 characters to be encoded.

RWByteOutputStream& 
getSinkStream();

const RWByteOutputStream& 
getSinkStream() const;

These functions return a reference to the binary stream that is used as the sink of bytes. They throw no exceptions.
