Public Interface ICacheRegionListener

public interface class ICacheRegionListener

Listeners receive notifications when a region is created or destroyed on another node. The methods on a ICacheRegionListener are invoked asynchronously. Listeners are change notifications that are invoked after the change has occured. Multiple events can cause concurrent invocation of ICacheRegionListener methods. If event A occurs before event B, there is no guarantee that their corresponding ICacheRegionListener method invocations will occur in the same order. Any exceptions thrown by the listener are caught by GemFire and logged. Listeners are user callbacks that are invoked by GemFire. It is important to ensure that minimal work is done in the listener before returning control back to GemFire. For example, a listener implementation may choose to hand off the event to a thread pool that then processes the event on its thread rather than the listener thread.
