| /** |
| * External system integration consists of common 'external system' functionality and external system-specific code. There are at |
| * least two approaches how to work with that external system-specific code: |
| * <pre> |
| * <ul> |
| * <li>use it from the ide process;</li> |
| * <li>create a slave process and perform external system-specific actions there;</li> |
| * </ul> |
| * </pre> |
| * <p/> |
| * E.g. when we work with particular external system api it might worth to do that at a separate process in order to avoid bad stuff |
| * like memory leaks to happen at the ide process. However, when external system-specific communication just starts new external |
| * system-process, there is no point in creating intermediate mediator process just to launch new process. |
| * <p/> |
| * That's why that stuff is covered by the current interface, i.e. different implementations are supposed to provide |
| * different 'in process' modes. |
