parse

public void parse(RenderContext context)

Description copied from interface: View

When a view has registered during rendering for parsing in the RenderContext the context will call this method on the next request. The view is responsible for parsing the request based on it's unique id and update models and sending events based on the request. In most cases the EventQueue should be used to send the events. This ensures that the models are all correctly updated before the events are actually processed. This is important since controllers (whom processes the events) must rely on this to process events correctly.
