Examples of org.grails.web.servlet.mvc.GrailsWebRequest

org.grails.web.servlet.mvc.GrailsWebRequest
Encapsulates a Grails request. An instance of this class is bound to the current thread using Spring's RequestContextHolder which can later be retrieved using: def webRequest = RequestContextHolder.currentRequestAttributes() @author Graeme Rocher @since 3.0
