public class sbsl

extends OSProcess

A Bot OS program that implements the Simple Bot Scripting Language (SBSL). The language is very simple. Each line of a script (.scr file) can either be a comment (it starts with a # in column 1) or a command. Commands can have arguments which are space separated on the line. If a string of space separated words needs to be treated as a single argument, then they may be quoted with double quotes ("). Commands can also run in the foreground or the background. A program that is to run as a background process ends with an ampersand (&).

Method Detail

initialize

public void initialize()

Description copied from class: OSProcess

This is called by the operating system during the initialization phase of the process. By default this method sets the process to the initialized state and returns. More sophisticated processes should override this method and place their initialization code here. When initialization is complete, a call to setInitialized with a value of true will set the process to its initialized state.

Overrides:

initialize in class OSProcess

run

public void run()
         throws OSProcessRelinquishControl,
                OSProcessLoadProcess,
                OSProcessExecProcess,
                OSProcessWaitForProcess,
                OSProcessDone

Description copied from class: OSProcess

The method that is called to do the real work of the process. The process should not hold the CPU forever, or no other processes will be able to run.

Overrides:

run in class OSProcess

Tags copied from class: OSProcess

Throws:

OSProcessRelinquishControl - thrown when the process wants to temporarily relinquish control and let another process run.

OSProcessDone - thrown when the process is finished.

OSProcessLoadProcess - thrown when the process is requesting that the operating system load a process for it.

OSProcessExecProcess - thrown when the process is requesting that the operating system load a process and replace it with the new process. This process exits by default.

OSProcessWaitForProcess - thrown when the process wants to wait for another process to complete before continuing to run.
