Method Detail

getPage

IPage getPage(IRequestCycle cycle,
              String pageName,
              IMonitor monitor)

Gets a given page for the engine. This may involve using a previously loaded page from a pool of available pages, or the page may be loaded as needed.

Parameters:

cycle - the current request cycle

pageName - the name of the page. May be qualified with a library id prefix, which may even be nested. Unqualified names are searched for extensively in the application namespace, and then in the framework namespace.

monitor - informed of any page loading activity

releasePage

void releasePage(IPage page)

Invoked after the engine is done with the page (typically, after the response to the client has been sent). The page is returned to the pool for later reuse.

reset

void reset()

Invoked to have the source clear any internal cache. This is most often used when debugging an application.

getResourceResolver

IResourceResolver getResourceResolver()
