Class java.nio.channels.ServerSocketChannel

Examples of java.nio.channels.ServerSocketChannel.accept()

java.nio.channels.ServerSocketChannel.accept()
Accepts a connection made to this channel's socket.
If this channel is in non-blocking mode then this method will immediately return null if there are no pending connections. Otherwise it will block indefinitely until a new connection is available or an I/O error occurs.
The socket channel returned by this method, if any, will be in blocking mode regardless of the blocking mode of this channel.
This method performs exactly the same security checks as the {@link java.net.ServerSocket#accept accept} method of the {@link java.net.ServerSocket} class. That is, if a security manager has beeninstalled then for each new connection this method verifies that the address and port number of the connection's remote endpoint are permitted by the security manager's {@link java.lang.SecurityManager#checkAccept checkAccept} method.
@return The socket channel for the new connection,or null if this channel is in non-blocking mode and no connection is available to be accepted @throws ClosedChannelException If this channel is closed @throws AsynchronousCloseException If another thread closes this channel while the accept operation is in progress @throws ClosedByInterruptException If another thread interrupts the current thread while the accept operation is in progress, thereby closing the channel and setting the current thread's interrupt status @throws NotYetBoundException If this channel's socket has not yet been bound @throws SecurityException If a security manager has been installed and it does not permit access to the remote endpoint of the new connection @throws IOException If some other I/O error occurs
