Method Detail

close

public void close()
           throws java.io.IOException

Description copied from class: NioChannel

Closes this channel.

Specified by:

close in interface java.lang.AutoCloseable

Specified by:

close in interface java.nio.channels.Channel

Specified by:

close in interface java.io.Closeable

Overrides:

close in class NioChannel

Throws:

java.io.IOException - If an I/O error occurs

isOpen

public boolean isOpen()

Description copied from class: NioChannel

Tells whether or not this channel is open.

Specified by:

isOpen in interface java.nio.channels.Channel

Overrides:

isOpen in class NioChannel

Returns:

true if, and only if, this channel is open

reset

public void reset(java.nio.channels.SocketChannel channel,
                  NioEndpoint.NioSocketWrapper socketWrapper)
           throws java.io.IOException

Description copied from class: NioChannel

Reset the channel

Overrides:

reset in class NioChannel

Parameters:

channel - the socket channel

socketWrapper - the socket wrapper

Throws:

java.io.IOException - If a problem was encountered resetting the channel

free
