In Java IO, an OutputStream can use flush() method to make sure data is sent at once.
Is there a corresponding function in Java NIO for SocketChannel? As far as I know, there is a force() method for FileChannel to flush data.
Might be a very naive question…
Use either
.force()or.getFD.sync()Update: Since you updated your question to be more specific on a SocketChannel (it was generally NIO), please see my reply instead.
