java NIO read/write independently

原文 2014-11-30 18:20:06 5 1 java/ nio

While Selector.select() waits in blocking mode for either of read/write ops, is it possible to push a write message to a client? How to move the Selector from blocking mode to write mode? The trigger could be a background thread placing data which needs to be written to a given channel.

Does Selector retain state of all the connections once they are accepted? Is it possible to have one thread solely for reading and other for writing?

While Selector.select() waits in blocking mode for either of read/write ops, is it possible to push a write message to a client?

Yes, just call write() .

How to move the Selector from blocking mode to write mode?

There is no such thing as write mode of a Selector.

Does Selector retain state of all the connections once they are accepted?

I don't know what this means, but you seem have a complete misunderstanding of how a Selector works.

Is it possible to have one thread solely for reading and other for writing?

Certainly, but in that case there is no point in using a Seector at all. You would be better off using Sockets and streams.

Read and Write Int using ByteBuffer in Java NIO

java nio cannot read after register a write operation

Querying java.nio.Buffer read/write (flip) state

java.nio.channels.SocketChannel for both periodic write and immediate read

Java NIO: Why the method names “read” “write” sounds the opposite?

single instance of java.nio AsynchronousSocketChannel for multiple read and write

Java nio partial read

Java nio read() return -1
