Package org.graylog2.lookup

Class LookupTableService

java.lang.Object

com.google.common.util.concurrent.AbstractIdleService

org.graylog2.lookup.LookupTableService

All Implemented Interfaces:

com.google.common.util.concurrent.Service

@Singleton
public class LookupTableService
extends com.google.common.util.concurrent.AbstractIdleService

This service maintains the in-memory adapters, caches and lookup table instances.

It initially loads all entities and starts them, and later reacts on event bus messages to reflect the current system state.
