Selector

public interface Selectable

An interface for asynchronous, multi-channel network I/O

Method Summary

void	close() Close this selector
java.util.List<NetworkReceive>	completedReceives() The list of receives that completed on the last poll() call.
java.util.List<NetworkSend>	completedSends() The list of sends that completed on the last poll() call.
void	connect(int id, java.net.InetSocketAddress address, int sendBufferSize, int receiveBufferSize) Begin establishing a socket connection to the given address identified by the given address
java.util.List<java.lang.Integer>	connected() The list of connections that completed their connection on the last poll() call.
void	disconnect(int id) Begin disconnecting the connection identified by the given id
java.util.List<java.lang.Integer>	disconnected() The list of connections that finished disconnecting on the last poll() call.
void	poll(long timeout, java.util.List<NetworkSend> sends) Initiate any sends provided, and make progress on any other I/O operations in-flight (connections, disconnections, existing sends, and receives)
void	wakeup() Wakeup this selector if it is blocked on I/O

Method Detail

connect

void connect(int id,
             java.net.InetSocketAddress address,
             int sendBufferSize,
             int receiveBufferSize)
             throws java.io.IOException

Begin establishing a socket connection to the given address identified by the given address

Parameters:

id - The id for this connection

address - The address to connect to

sendBufferSize - The send buffer for the socket

receiveBufferSize - The receive buffer for the socket

Throws:

java.io.IOException - If we cannot begin connecting

disconnect

void disconnect(int id)

Begin disconnecting the connection identified by the given id

wakeup

void wakeup()

Wakeup this selector if it is blocked on I/O

close

void close()

Close this selector

poll

void poll(long timeout,
          java.util.List<NetworkSend> sends)
          throws java.io.IOException

Initiate any sends provided, and make progress on any other I/O operations in-flight (connections, disconnections, existing sends, and receives)

Parameters:

timeout - The amount of time to block if there is nothing to do

sends - The new sends to initiate

Throws:

java.io.IOException

completedSends

java.util.List<NetworkSend> completedSends()

completedReceives

java.util.List<NetworkReceive> completedReceives()

The list of receives that completed on the last poll() call.

disconnected

java.util.List<java.lang.Integer> disconnected()

The list of connections that finished disconnecting on the last poll() call.

connected

java.util.List<java.lang.Integer> connected()

The list of connections that completed their connection on the last poll() call.
