"Java" "NiO" 10, Java NiO serversocketchannel

Java NiO's Serversocketchannel is the channel used to listen for incoming TCP connections, and it wants to serversocket in a standard Java network. Examples are as follows:

Serversocketchannel Serversocketchannel = Serversocketchannel.open (); Serversocketchannel.socket (). Bind (New Inetsocketaddress (8090)); while (true) {Socketchannel Socketchannel = Serversocketchannel.accept ();}

Open a Serversocketchannel

Open by opening method

Serversocketchannel Serversocketchannel = Serversocketchannel.open ();

Close Serversocketchannel

Through the Close method

Monitor Inbound connections

Listen for foreign connections by calling the Accept method, when the Accept method returns, a connected Socketchannel is returned. So the Accept method blocks until there is a connection.

Because the general situation is not interested in listening to a single connection, you can call the Accept method within the loop.

while (true) {Socketchannel Socketchannel = Serversocketchannel.accept ();}

Of course, you should use some exit loop conditions instead of true.

Non-blocking mode

Serversocketchannel can be set to non-blocking mode, in non-blocking mode, the Accept method returns immediately, it is possible to return NULL if there is no connection established. So you have to check that the returned Socketchannel is not NULL. As follows:

while (true) {Socketchannel Socketchannel = serversocketchannel.accept (); if (Socketchannel!=null) {}}
