Class CacheScheduler.EntryImpl<T extends ExtractionNamespace>

java.lang.Object

io.druid.server.lookup.namespace.cache.CacheScheduler.EntryImpl<T>

All Implemented Interfaces:

AutoCloseable

Enclosing class:

CacheScheduler

public class CacheScheduler.EntryImpl<T extends ExtractionNamespace>
extends Object
implements AutoCloseable

This class effectively contains the whole state and most of the logic of CacheScheduler.Entry, need to be a separate class because the Entry must not be referenced from the runnable executed in CacheScheduler.cacheManager's ExecutorService, that would be a leak preventing the Entry to be collected by GC, and therefore entryCleaner to be run by the JVM. Also, entryCleaner must not reference the Entry through it's Runnable hunk.
