Class ConsoleThread

  +--org.erights.e.extern.file.ConsoleThread

All Implemented Interfaces:

Runnable

public class ConsoleThread

extends Object

implements Runnable

Untamed: Implements a seperate thread to manage the user console (i.e., the keyboard and tty). This needs to be in its own thread so that the user pondering what to type next doesn't block the entire E runQ!

The console is given an input handler when it is created, which is an object that implements the ConsoleInputHandler interface. Each line of input typed on the console is sent as a String in an E-message to the input handler. End of file is signalled to the input handler by sending it a null. If a problem is thrown while reading, the handler is asked to handle it as well.
