public abstract class CSingletonApplication

extends CApplication

Create a singleton application invoked by CJavaMenuItem widget. Initializes a connection to a server, typically a gateway such as cdevGateway if it is not connected.

The child class must provide a null constructor and the main method. It is also necessary to verwite the setArgs(String[]) method if there is any argument needed to be passed.

CsingletonApplication is a subclass of CApplication and has a static class pointer defined to keep tracking the instance. Only one instance will be invoked in same virtue machine if the application extends the CSingleApplication. When more instances are needed it is better to using the CNamedApplication as the parent class.
