| * Listeners are notified of events occurring in a PDA program |
| * being interpreted. |
| * <p> |
| * The events generated by the interpreter are: |
| * <ul> |
| * <li><code>started</code> - the interpreter has started (guaranteed to be the |
| * first event sent)</li> |
| * <li><code>terminated</code> - the interpreter has terminated (guaranteed to be |
| * the last event sent)</li> |
| * <li><code>suspended X</code> - the interpreter has suspended and entered debug mode; |
| * <code>X</code> is the cause of the suspension: |
| * <ul> |
| * <li><code>breakpoint N</code> - a breakpoint at line <code>N</code> was hit</li> |
| * <li><code>client</code> - a client request to suspend has completed</li> |
| * <li><code>drop</code> - a client request to drop a frame has completed</li> |
| * <li><code>event E</code> - an error was encountered, where <code>E</code> is one |
| * of <code>unimpinstr</code> or <code>nosuchlabel</code></li> |
| * <li><code>step</code> - a step request has completed</li> |
| * <li><code>watch A F::V</code> - a watchpoint was hit for reason <code>A</code> |
| * (<code>read</code> or <code>write</code>), on variable <code>V</code> in |
| * function <code>F</code></li> |
| * </ul> |
| * </li> |
| * <li><code>resumed X</code> - the interpreter has resumed execution in run mode; |
| * <code>X</code> is the cause of the resume: |
| * <ul> |
| * <li><code>step</code> - a step request has been initiated</li> |
| * <li><code>client</code> - a client request to resume has been initiated</li> |
| * </ul> |
| * </li> |
| * <li><code>unimplemented instruction X</code> - an unimplemented instruction <code>X</code> |
| * was encountered</li> |
| * <li><code>no such label X</code> - a branch or call to an unknown label <code>X</code> |
| * was encountered</li> |
| * </ul> |
