Method Summary

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).
IPage	loadPage(String name, INamespace namespace, IRequestCycle cycle, IComponentSpecification specification) Invoked by the IPageSourceto load a specific page.
void	loadTemplateForComponent(IRequestCycle cycle, ITemplateComponent component) Invoked by a component (from within its IComponent.finishLoad(IRequestCycle, IPageLoader, IComponentSpecification)method) to load the template for the component.

Method Detail

createImplicitComponent

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

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

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

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

void loadTemplateForComponent(IRequestCycle cycle,
                              ITemplateComponent component)

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.

Since:

4.0
