    • removeCommand

      public void removeCommand(org.osgi.framework.ServiceReference ref)

    • executeCommand

      public void executeCommand(String commandLine, PrintStream out, PrintStream err) throws Exception
      Description copied from interface: ShellService
      This method executes the supplied command line using the supplied output and error print stream. The assumption of this method is that a command line will be typed by the user (or perhaps constructed by a GUI) and passed into it for execution. The command line is interpretted in a very simplistic fashion; it takes the leading string of characters terminated by a space character (not including it) and assumes that this leading token is the command name. For an example, consider the following command line: 

           update 3 http://www.foo.com/bar.jar

      This is interpretted as an update command; as a result, the entire command line (include command name) is passed into the execute() method of the command service with the name update if one exists. If the corresponding command service is not found, then an error message is printed to the error print stream.

      Specified by:
      executeCommand in interface ShellService
      Specified by:
      executeCommand in interface ShellService
      Parameters:
      commandLine - the command line to execute.
      out - the standard output print stream.
      err - the standard error print stream.
      Throws:
      Exception
