Method Detail

init

public void init(HttpServletRequest request,
                 HttpServletResponse response)

Description copied from interface: JspBacking

This method is called once per request, and backing files can do request-scoped initialization by implementing this method. This method is run on the window (book/page/portlet) even if the window is not currently on a selected page.

Specified by:

init in interface JspBacking

Parameters

request - HTTP request

response - HTTP response

handlePostbackData

public boolean handlePostbackData(HttpServletRequest request,
                                  HttpServletResponse response)

Description copied from interface: JspBacking

The purpose of this method is to let an implementation process request data.

This method should return true if it changes the window mode, window state, or the current page.

Specified by:

handlePostbackData in interface JspBacking

Parameters

request - HTTP request

response - HTTP response

Returns

boolean true if the window mode, state, or current page were changed

preRender

public boolean preRender(HttpServletRequest request,
                         HttpServletResponse response)

Description copied from interface: JspBacking

This method is called before rendering the JSP that this backing file is associated with. This method will not be run if the book/page/portlet is not being rendered (displayed). This is useful if heavy business logic only needs to be run if this portlet is on a selected page.

This method should return true to let the framework render the JSP. If this method returns false, the framework will not render the content JSP.

Note: if you don't want the Window (book, page or portlet) to render at all, call setVisible(false) on the backing context.

Specified by:

preRender in interface JspBacking

Parameters

request - HTTP request

response - HTTP response

Returns

boolean true if the content JSP should be rendered.

Description copied from interface: JspBacking
