RWSynchronizedCharInputStreamImp()

#include <rw/stream/RWSynchronizedCharInputStreamImp.h>

Class RWSynchronizedCharInputStreamImp implements a simple lock stream that is used with narrow 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.

RWSynchronizedCharInputStreamImp(RWCharInputStream&
                                 sourceStream);

Initializes the reference to the input stream that will be used as the source of narrow characters.

Parameter List

sourceStream

The input stream that will serve as the source of narrow characters.

static RWCharInputStream 
make(RWCharInputStream& sourceStream);

Constructs an RWSynchronizedCharInputStreamImp instance that uses sourceStream as its source of narrow characters, and returns a handle to it. Throws no exceptions.

Parameter List

sourceStream

The output stream that will serve as the source of narrow characters.

virtual void 
readUntil(RWCString& string, char delim);

Reads narrow characters from the stream until the last narrow character read is equal to delim, or the end of the input sequence is reached. The narrow characters read are stored in a string object.

Parameter List

string	The string object receiving the characters extracted from the stream.
delim	The narrow character used as a delimiter.
