public class ReadlineReader extends Reader
AReader
wrapper for the Readline classes. This seems to work fine in conjunction with such classes as BufferedReader, but it hasn't been tested well enough to see if this will work well in all cases. This was implemented to make it easier to supplant Readline's functionality [shrug] anywhere and everywhere, but specifically in BeanShell.- Version:

read
public int read(char[] cbuf, int off, int len) throws IOException
Reads what's given fromreadline()
into a buffer. When that buffer is emptied,readline()
is called again to replenish that buffer. This seems to work fine in conjunction with such classes as BufferedReader, but it hasn't been tested well enough to see if this will work well in all cases.- Specified by:
