Package io.vertx.reactivex.core.net

Class NetSocket

  • All Implemented Interfaces:
    ReadStream<Buffer>, StreamBase, WriteStream<Buffer>
    public class NetSocket
extends Object
implements ReadStream<Buffer>, WriteStream<Buffer>
    Represents a socket-like interface to a TCP connection on either the client or the server side.

    Instances of this class are created on the client side by an NetClient when a connection to a server is made, or on the server side by a NetServer when a server accepts a connection.

    It implements both and so it can be used with Pipe to pipe data with flow control.

    NOTE: This class has been automatically generated from the original non RX-ified interface using Vert.x codegen.

      • write

        public Future<Void> write​(Buffer data)
        Write some data to the stream.

        The data is usually put on an internal write queue, and the write actually happens asynchronously. To avoid running out of memory by putting too much on the write queue, check the WriteStream.writeQueueFull() method before writing. This is done automatically if using a .

        When the data is moved from the queue to the actual medium, the returned will be completed with the write result, e.g the future is succeeded when a server HTTP response buffer is written to the socket and failed if the remote client has closed the socket while the data was still pending for write.

        Specified by:
        write in interface WriteStream<Buffer>
        Parameters:
        data - the data to write
        Returns:

        Parameters:
        endHandler -

        public NetSocket setWriteQueueMaxSize​(int maxSize)
        Description copied from interface: WriteStream

        The value is defined by the implementation of the stream, e.g in bytes for a NetSocket, etc...

        Specified by:
        setWriteQueueMaxSize in interface WriteStream<Buffer>
        Parameters:
        maxSize - the max size of the write stream

        public NetSocket drainHandler​(Handler<Void> handler)
        Description copied from interface: WriteStream
        Set a drain handler on the stream. If the write queue is full, then the handler will be called when the write queue is ready to accept buffers again. See Pipe for an example of this being used.

        The stream implementation defines when the drain handler, for example it could be when the queue size has been reduced to maxSize / 2.

        Specified by:
        drainHandler in interface WriteStream<Buffer>
        Parameters:
        handler - the handler
        Returns:
        a reference to this, so the API can be used fluently

      • writeHandlerID

        public String writeHandlerID()
        When a NetSocket is created, it may register an event handler with the event bus, the ID of that handler is given by writeHandlerID.

        By default, no handler is registered, the feature must be enabled via NetClientOptions or NetServerOptions.

        Given this ID, a different event loop can send a buffer to that event handler using the event bus and that buffer will be received by this instance in its own event loop and written to the underlying connection. This allows you to write data to other connections which are owned by different event loops.

        Returns:
        the write handler ID
