Interface CommandConverter

public interface CommandConverter

Purpose: Define a pluggable conversion interface that can be supplied by the application

Description: The implementation class of this interface should be set on the remote command manager through the setCommandConverter() method. The implementation class will get invoked, through its convertToEclipseLinkCommand(), to convert the application command format into a TopLink Command object that can be propagated throughout the cluster. Similarly, convertToUserCommand() will be invoked on the implementation class to give the application an opportunity to convert the EclipseLink Command object into an object that is suitable for being processed by the application.
