All Implemented Interfaces:

Serializable, Comparable<GridEvent>, GridEvent

public class GridAuthorizationEvent
extends GridEventAdapter

Grid authorization event.

Grid events are used for notification about what happens within the grid. Note that by design GridGain keeps all events generated on the local node locally and it provides APIs for performing a distributed queries across multiple nodes:

• GridEvents.remoteQuery(GridPredicate, long, int...) - asynchronously querying events occurred on the nodes specified, including remote nodes.
• GridEvents.localQuery(GridPredicate, int...) - querying only local events stored on this local node.
• GridEvents.localListen(GridPredicate, int...) - listening to local grid events (events from remote nodes not included).

User can also wait for events using method GridEvents.waitForLocal(GridPredicate, int...).

Events and Performance

It is highly recommended to enable only those events that your application logic requires by using GridConfiguration.getIncludeEventTypes() method in GridGain configuration. Note that certain events are required for GridGain's internal operations and such events will still be generated but not stored by event storage SPI if they are disabled in GridGain configuration.
