#include <rw/stream/RWUCharToByteOutputStreamImp.h>

Concrete class connecting a Unicode character stream to a binary stream. The UTF-16 characters are written as a sequence of bytes using the byte ordering (little endian, or big endian) supported by the system on which the code is executed. The UTF-16 character U+FEFF is inserted in the stream as first character to let input streams figure out the byte ordering used when generating the output byte sequence. Implements the body idiom from the handle-body pattern.

RWUCharToByteOutputStreamImp(RWByteOutputStream& sinkStream);

Initializes the reference to the binary stream that will be used as the sink of bytes, and writes the stream header (U+FEFF).

Parameter List

sinkStream

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

virtual 
~RWUCharToByteOutputStreamImp();

Destructor.

static RWUCharOutputStream 
make(RWByteOutputStream& sink);

Constructs an RWUCharToByteOutputStreamImp instance that uses sink as its sink of bytes, and returns a handle to it.

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);

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 written.

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

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 written.

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.
