Method Detail

postHandle

void postHandle(org.springframework.web.context.request.WebRequest request,
              org.springframework.web.servlet.ModelAndView modelAndView,
              String componentPath)

Initialize a Postprocessor for the given request. Typical use cases are population of selection options or showing aggregations of the list (sums of elements, totals, ...) An implementation can retrieve the segment from the componentPath example: PageableList list = (PageableList) ComponentUtils.getComponent(modelAndView, componentPath); // finally contribute to modelAndView if (modelAndView != null) { // should be checked because the same segment may occur multiple times modelAndView("someName", someObject); } There are lots of examples in the shept demo implementations. Postprocessors should usually be located in the ../web/controller/postprocessors package of your app.

Parameters:

request - the web request that the data binding happens within

modelAndView - the ModelAndView

componentPath - the path within the bound object
