Interface Server<A>

Type Parameters:

A - The type of the address, e.g. Address

All Known Implementing Classes:

BaseServer, NioServer, TcpServer

public interface Server<A>

NIO based server interface for sending byte[] buffers to a single or all members and for receiving byte[] buffers. Implementations should be able to be used to provide light weight NIO servers.

Method Detail

receiver

Server<A> receiver(Receiver<A> receiver)

Sets a receiver

Parameters:

receiver - The receiver

start

void start()
    throws java.lang.Exception

Throws:

java.lang.Exception

stop

void stop()

Stops the server, e.g. by killing the thread calling select()

send

          byte[] buf,
          int offset,
          int length)
   throws java.lang.Exception

Sends a message to a destination

Parameters:

dest - The destination address. Must not be null

buf - The buffer

offset - The offset into the buffer

length - The number of bytes to be sent

Throws:

send

void send(A dest,
          java.nio.ByteBuffer buf)
   throws java.lang.Exception
