Class PageLoader

java.lang.Object
  org.apache.tapestry.pageload.PageLoader

All Implemented Interfaces:

IPageLoader

public class PageLoader
extends Object
implements IPageLoader

Implementation of tapestry.page.PageLoader. Runs the process of building the component hierarchy for an entire page.

This implementation is not threadsafe, therefore the pooled service model must be used.

createImplicitComponent

public IComponent createImplicitComponent(IRequestCycle cycle,
                                          IComponent container,
                                          String componentId,
                                          String componentType,
                                          org.apache.hivemind.Location location)

Invoked to create an implicit component (one which is defined in the containing component's template, rather that in the containing component's specification).

loadPage

public IPage loadPage(String name,
                      INamespace namespace,
                      IRequestCycle cycle,
                      IComponentSpecification specification)

Description copied from interface: IPageLoader

Invoked by the IPageSourceto load a specific page. This method is not reentrant. The page is immediately attached to the engine.

Specified by:

loadPage in interface IPageLoader

Parameters:

name - the simple (unqualified) name of the page to load

namespace - from which the page is to be loaded (used when resolving components embedded by the page)

cycle - the request cycle the page is initially loaded for (this is used to define the locale of the new page, and provide access to the corect specification source, etc.).

specification - the specification for the page

loadTemplateForComponent

public void loadTemplateForComponent(IRequestCycle cycle,
                                     ITemplateComponent component)

Description copied from interface: IPageLoader

Invoked by a component (from within its IComponent.finishLoad(IRequestCycle, IPageLoader, IComponentSpecification)method) to load the template for the component. This will result in new components being created, and the "outers" of the component being updated.

Specified by:

loadTemplateForComponent in interface IPageLoader

Since:

4.0
