MTStream

Class MTStream is an abstract class and is not intended to be instantiated but to serve as a root class to all sorts of streams, like implemented in classes MTFileStream (5.2) and MTCompressedFileStream (5.2). This ensures, that everything that accepts a stream for input or output follows the defined interface of class MTStream, whether it is a MTFileStream or a MTCompressedStream.

Methods:

* test
-(BOOL)ok	returns true if the stream is still valid
* operation
-(void)close	close the stream and invalidate it
* write access
-(void)writeCString: (const char*)string	write C string to the stream
-(void)writeData: (NSData*)data	write data to the stream
-(void)writeString: (NSString*)string	write string to the stream
* read access
-(NSData*)readLength: (unsigned int)len	read data with maximum length from stream
-(NSData*)readLineLength: (unsigned int)len	read data line up to the end of line or maximum length
-(NSString*)readStringLineLength: (unsigned int)len	read string up to the end of line or maximum length
