Detailed Description

Class RWSynchronizedUCharInputStreamImp implements a simple lock stream that is used with UTF-16 character input stream. The stream locks its internal synchronization mechanism before forwarding input requests to its associated source stream, and then unlocks the internal synchronization mechanism upon completion. The stream's internal synchronization mechanism is locked using a guard object, ensuring its proper release in the event that an exception is thrown.

Constructor & Destructor Documentation

RWSynchronizedUCharInputStreamImp::RWSynchronizedUCharInputStreamImp ( const RWUCharInputStream & sourceStream )

protected

Initializes the reference to the input stream that will be used as the source of UTF-16 characters.

Parameters

sourceStream The input stream that will serve as the source of UTF-16 characters.

Member Function Documentation

static RWUCharInputStream RWSynchronizedUCharInputStreamImp::make ( const RWUCharInputStream & sourceStream )

inlinestatic

Constructs an RWSynchronizedUCharInputStreamImp instance that uses sourceStream as its source of UTF-16 characters, and returns a handle to it. Throws no exceptions.

Parameters

sourceStream The output stream that will serve as the source of UTF-16 characters.

virtual RWSize RWSynchronizedUCharInputStreamImp::readUntil	(	RWUChar *	unicodeArray,
		RWSize	maxSize,
		RWUChar	delim
	)

virtual

Reads UTF-16 characters from the attached source stream until the last UTF-16 character read is equal to delim, or maxSize UTF-16 characters have been read, or the end of the input sequence is reached. The UTF-16 characters read are stored in unicodeArray. The function returns the actual number of UTF-16 characters read from the stream.

Parameters

unicodeArray	A pointer to the array receiving the UTF-16 character(s) extracted from the stream.
maxSize	The maximum number of UTF-16 character(s) to be read.
delim	The UTF-16 character used as a delimiter.

Reimplemented from RWFilteredUCharInputStreamImp.
