Interface IpModem<I,​O>

  • All Known Implementing Classes:
    AbstractIpModem, HttpClientModem, HttpServerModem, MqttSocketModem, WebSocketModem
    public interface IpModem<I,​O>
    Network socket binding that provides asynchronous I/O decoders and encoders for a non-blocking NIO network channel.

    An IpModem interfaces with the underlying asynchronous networking system via an IpModemContext. The modem context invokes I/O callbacks on the IpModem when the underlying network socket is ready to perform I/O operations permitted by the socket context's FlowControl.

    • Method Detail

      • ipModemContext

        IpModemContext<I,​O> ipModemContext()
        Returns the socket modem context to which this IpModem is bound; returns null if this IpModem is unbound.

      • setIpModemContext

        void setIpModemContext​(IpModemContext<I,​O> context)
        Sets the socket modem context to which this IpModem is bound.

      • idleTimeout

        long idleTimeout()
        Returns the number of idle milliseconds after which this IpModem should be closed due to inactivity. Returns -1 if a default idle timeout should be used. Returns 0 if the underlying network socket should not time out.

      • doRead

        void doRead()
        I/O callback invoked by the modem context asking this IpModem to provide an input Decoder by invoking the modem context's read method. The modem context will asynchronously feed input data to the provided read Decoder until it transitions out of the cont state. The read flow control of the underlying network socket is automatically managed by the modem context using the state of the read Decoder. May be invoked concurrently to other I/O callbacks, but never concurrently with other doRead or didRead calls.

      • didRead

        void didRead​(I input)
        I/O callback invoked by the modem context with the completed value of the current read Decoder after it has transitioned to the done state. May be invoked concurrently to other I/O callbacks, but never concurrently with other doRead or didRead calls.

      • doWrite

        void doWrite()
        I/O callback invoked by the modem context asking this IpModem to provide an output Encoder by invoking the modem context's write method. The modem context will asynchronously pull output data from the provided write Encoder until it transitions out of the cont state. The write flow control of the underlying network socket is automatically managed by the modem context using the state of the write Encoder. May be invoked concurrently to other I/O callbacks, but never concurrently with other doWrite or didWrite calls.

      • didWrite

        void didWrite​(O output)
        I/O callback invoked by the modem context with the completed value of the current write Encoder after it has transitioned to the done state. May be invoked concurrently to other I/O callbacks, but never concurrently with other dodWrite or didWrite calls.

      • willConnect

        void willConnect()
        Lifecycle callback invoked by the modem context before the underlying network socket attempts to open a connection.

      • didConnect

        void didConnect()
        Lifecycle callback invoked by the modem context after the underlying network socket has opened a connection.

      • willSecure

        void willSecure()
        Lifecycle callback invoked by the modem context before the underlying network socket establishes a secure connection.

      • didSecure

        void didSecure()
        Lifecycle callback invoked by the modem context after the underlying network socket has established a secure connection.

      • willBecome

        void willBecome​(IpSocket socket)
        Lifecycle callback invoked by the modem context before it has become a new socket implementation.

      • didBecome

        void didBecome​(IpSocket socket)
        Lifecycle callback invoked by the modem context after it has become a new socket implementation.

      • didTimeout

        void didTimeout()
        Lifecycle callback invoked by the modem context after the underlying network connection has timed out. The modem will automatically be closed.

      • didDisconnect

        void didDisconnect()
        Lifecycle callback invoked by the socket context after the underlying network connection has disconnected.

      • didFail

        void didFail​(Throwable error)
        Lifecycle callback invoked by the modem context when the underlying network socket fails by throwing an error. The modem will automatically be closed.
