Class SimpleShellContext

java.lang.Object
  org.overlord.sramp.shell.api.SimpleShellContext

All Implemented Interfaces:

ShellContext

public class SimpleShellContext
extends Object
implements ShellContext

A simple implementation of ShellContext. This implementation does not implement any of the event handling. The purpose of this class is to provide a very simple implementation of the shell context in case users wish to execute shell commands from outside the interactive shell runtime environment. In other words, it's useful when utilizing the shell command as a standalone Java app.
