ReadLn is an abstract virtual String function that specifies the method used to read a line of data from the stream.
AMaxLineLength indicates the maximum line length allowed when reading from the stream. The default value is -1, and indicates that all data up to an end-of-stream or an EOL character sequence is used when reading from the stream.
AExceptionIfEOF indicates if an exception is raised when an unexpected end of stream is encountered. The default value is False.
ReadLn must be implemented in a descendant class that provides access to a stream implentation for the platform or Operating System.
