io.datakernel.eventloop

Class AbstractServer<S extends AbstractServer<S>>

java.lang.Object

io.datakernel.eventloop.AbstractServer<S>

Type Parameters:

S - type of AbstractNioServer which extends from it

All Implemented Interfaces:

EventloopServer, WorkerServer, EventloopJmxMBean, EventloopJmxMBeanEx, Initializable<S>

Direct Known Subclasses:

PrimaryServer, SimpleServer

public abstract class AbstractServer<S extends AbstractServer<S>>
extends Object
implements EventloopServer, WorkerServer, Initializable<S>, EventloopJmxMBeanEx

It is implementation of EventloopServer. It is non-blocking server which works in eventloop. The server runs on the one thread, and all events are fired on that thread. This server can listen few addresses in one time and you can register multiple connections for responding to incoming data.
