| * The Connector Service should be called to create and open |
| * {@code javax.microedition.io.Connection} objects. |
| * |
| * When an {@code open*} method is called, the implementation of the Connector |
| * Service will examine the specified name for a scheme. The Connector Service |
| * will then look for a Connection Factory service which is registered with the |
| * service property {@code IO_SCHEME} which matches the scheme. The |
| * {@code createConnection} method of the selected Connection Factory will then |
| * be called to create the actual {@code Connection} object. |
| * |
| * <p> |
| * If more than one Connection Factory service is registered for a particular |
| * scheme, the service with the highest ranking (as specified in its |
| * {@code service.ranking} property) is called. If there is a tie in ranking, |
| * the service with the lowest service ID (as specified in its |
| * {@code service.id} property), that is the service that was registered first, |
| * is called. This is the same algorithm used by |
| * {@code BundleContext.getServiceReference}. |
