Method Detail

onInitialize

protected void onInitialize()
Description copied from class: Component
This method is meant to be used as an alternative to initialize components. Usually the component's constructor is used for this task, but sometimes a component cannot be initialized in isolation, it may need to access its parent component or its markup in order to fully initialize. This method is invoked once per component's lifecycle when a path exists from this component to the Page thus providing the component with an atomic callback when the component's environment is built out.

Overrides must call super#Component.onInitialize(). Usually this should be the first thing an override does, much like a constructor.

Parent containers are guaranteed to be initialized before their children

It is safe to use Component.getPage() in this method

NOTE:The timing of this call is not precise, the contract is that it is called sometime before Component.onBeforeRender().

Overrides:
onInitialize in class Component

getCss

protected ResourceReference getCss()
Override this to provide your own CSS, or return null to avoid including the default.

Returns:
ResourceReference for your CSS.

renderHead

public void renderHead(IHeaderResponse response)
Description copied from interface: IHeaderContributor
Render to the web response whatever the component wants to contribute to the head section. TODO: Post 1.3, add component parameter, so that the behaviors dont' have to track component instances

Specified by:
renderHead in interface IHeaderContributor
Parameters:
response - Response object
