Method Detail

addOuter

public void addOuter(IRender element)

Adds an element as an outer element for the receiver. Outer elements are elements that should be directly rendered by the receiver's render() method. That is, they are top-level elements on the HTML template.

Specified by:

addOuter in interface ITemplateComponent

renderComponent

protected void renderComponent(IMarkupWriter writer,
                               IRequestCycle cycle)

Renders the top level components contained by the receiver.

Specified by:

renderComponent in class AbstractComponent

Since:

2.0.3

finishLoad

public void finishLoad(IRequestCycle cycle,
                       IPageLoader loader,
                       IComponentSpecification specification)

Loads the template for the component, then invokes AbstractComponent.finishLoad(IRequestCycle, IPageLoader, IComponentSpecification). Subclasses must invoke this method first, before adding any additional behavior, though its usually simpler to override AbstractComponent.finishLoad()instead.

Specified by:

finishLoad in interface IComponent

Overrides:

finishLoad in class AbstractComponent
