Detailed Description

Concrete class connecting a UTF-16 character stream to a UTF-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.

static RWUCharOutputStream RWUCharToUTF8ByteOutputStreamImp::make

(

const RWByteOutputStream &

sink

)

[inline, static]

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

Parameters:

sink

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

virtual void RWUCharToUTF8ByteOutputStreamImp::write	(	const RWUChar *	unicodeArray,
		RWSize	numUChars
	)			[virtual]

Encodes, and 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 encoded.

Implements RWUCharOutputStreamImp.

virtual void RWUCharToUTF8ByteOutputStreamImp::write

(

RWUChar

unicodeValue

)

[virtual]

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

Parameters:

unicodeValue

The UTF-16 character to be encoded.

Implements RWUCharOutputStreamImp.
