Class AbstractLifecycleEventLoop

java.lang.Object

net.openhft.chronicle.core.io.AbstractCloseable

net.openhft.chronicle.threads.AbstractLifecycleEventLoop

All Implemented Interfaces:

Closeable, AutoCloseable, net.openhft.chronicle.core.io.ManagedCloseable, net.openhft.chronicle.core.io.QueryCloseable, net.openhft.chronicle.core.io.ReferenceOwner, net.openhft.chronicle.core.threads.EventLoop

Direct Known Subclasses:

BlockingEventLoop, EventGroup, MediumEventLoop, MonitorEventLoop

public abstract class AbstractLifecycleEventLoop
extends net.openhft.chronicle.core.io.AbstractCloseable
implements net.openhft.chronicle.core.threads.EventLoop

A parent class that:

• Enforces the life-cycle of an EventLoop
• Implements idempotency for start(), stop()
• Ensures stop() only returns when the EventLoop is stopped

See EventLoopLifecycle for details of the life-cycle
