Examples of org.apache.tapestry5.ComponentResources

org.apache.tapestry5.ComponentResources
Provides a component instance with the resources provided by the framework. In many circumstances, the resources object can be considered the component itself; in others, it is the {@linkplain #getComponent() component property}, an instance of a class provided by the application developer (though transformed in many ways while being loaded) that is the true component. In reality, it is the combination of the resources object with the user class instance that forms the components; neither is useful without the other.
