| * Defines common contract for a strategy which is able to manage project data defines in terms of 'external systems' sub-system. |
| * <p/> |
| * Implementations of this interface are expected to be thread-safe. |
| * <p/> |
| * <b>Note:</b> there is a possible case that more than one service is registered for the same key, e.g. there is a built-in |
| * generic service and a plugin provides custom extension to it. Platform calls all of them then. That means that project data |
| * service implementation must be ready to the following: |
| * <pre> |
| * <ul> |
| * <li>target data is already imported by another service (just no-op then);</li> |
| * <li> |
| * provide a hint about the order in which the services for the same key should be processed. That is done by marking |
| * it by {@link Order} annotation where the smaller value corresponds to earlier execution; |
| * </li> |
