Detailed Description

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.

Constructor & Destructor Documentation

virtual RWUCharToByteOutputStreamImp::~RWUCharToByteOutputStreamImp

(

)

[virtual]

Destructor.

RWUCharToByteOutputStreamImp::RWUCharToByteOutputStreamImp

(

const RWByteOutputStream &

sinkStream

)

[protected]

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

Parameters:

sinkStream

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

Implements RWStreamImp.

static RWUCharOutputStream RWUCharToByteOutputStreamImp::make

(

const RWByteOutputStream &

sink

)

[inline, static]

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

Parameters:

sink

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

virtual void RWUCharToByteOutputStreamImp::write	(	const RWUChar *	unicodeArray,
		RWSize	numUChars
	)			[virtual]

Writes an array of UTF-16 characters to the stream used as the sink of bytes.

Parameters:

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

Implements RWUCharOutputStreamImp.

virtual void RWUCharToByteOutputStreamImp::write

(

RWUChar

unicodeValue

)

[virtual]

Writes a single UTF-16 character to the binary stream used as the sink of bytes.

Parameters:

unicodeValue

The UTF-16 character to be written.

Implements RWUCharOutputStreamImp.
