Interface ConnectorService

public interface ConnectorService

The Connector Service should be called to create and open javax.microedition.io.Connection objects. When an 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 IO_SCHEME which matches the scheme. The createConnection method of the selected Connection Factory will then be called to create the actual Connection object.

If more than one Connection Factory service is registered for a particular scheme, the service with the highest ranking (as specified in its service.ranking property) is called. If there is a tie in ranking, the service with the lowest service ID (as specified in its service.id property), that is the service that was registered first, is called. This is the same algorithm used by BundleContext.getServiceReference.
