org.wso2.carbon.registry.core.jdbc.handlers.builtin.SymLinkHandler
public class SymLinkHandler
This handler is used to create a symbolic link from one resource to another and perform registry operations on the symbolic link and have them applied on the actual resource as if the actual resource itself was being used. The symbolic link handler plays a key role to make it possible to create and work with symbolic links via the user interface.
