public interface ChannelFutureListener extends EventListener
ChannelFuture
. The result of the
asynchronous Channel
I/O operation is notified once this listener
is added by calling ChannelFuture.addListener(ChannelFutureListener)
.
operationComplete(ChannelFuture)
is directly called by an I/O
thread. Therefore, performing a time consuming task or a blocking operation
in the handler method can cause an unexpected pause during I/O. If you need
to perform a blocking operation on I/O completion, try to execute the
operation in a different thread using a thread pool.Modifier and Type | Field and Description |
