/**
* This class provides an empty implementation of the OperationHandler interface, to
* minimize the effort required to implement this interface.
*
* Subclasses only need to override those methods that are needed to handle the expected operations
* for the corresponding remote type. Methods that are not overridden will throw an
* {@link UnsupportedOperationException}.
*
*
* It is recommended to extend this base class rather than to implement the OperationHandler
* interface itself.
*
*
* Note: The classes and interfaces in the package
* org.eclipse.rap.rwt.remote are still considered provisional. They are
* expected to evolve over the next releases, which may lead to slight changes. We make the package
* available to enable the development of custom components with the new API.
