public abstract class BubbleEvent extends GEvent
Abstract class extending the base GEvent to set the event propagation to sinking, i.e. an event send from child to parent.

Sinking events are typically used when a parent wishes to inform children of something, or by means of a "messaging system" to let e.g. an event collect information from potential event listeners, a good example would be QueryReferencesEvent, and ResolveReferencesEvent.
