Interface Connection

  • All Superinterfaces:
    java.lang.AutoCloseable
    All Known Implementing Classes:
    ClientConnection
    public interface Connection
extends java.lang.AutoCloseable
    Top level Connection object that can be used as a stand alone API for sending messages and creating Receiver instances for message consumption. The Connection API also exposes a Session based API for more advanced messaging use cases. When a Connection is closed all the resources created by the connection are implicitly closed.

    • Method Detail

      • openFuture

        java.util.concurrent.Future<Connection> openFuture()
        When a Connection is created it may not be opened on the remote peer, the future returned from this method allows the caller to await the completion of the Connection open by the remote before proceeding on to other messaging operations. If the open of the connection fails at the remote an Exception is thrown from the Future.get() method when called.
        Returns:
        a Future that will be completed when the remote opens this Connection.

      • close

        void close()
        Requests a close of the Connection at the remote and waits until the Connection has been fully closed or until the configured ConnectionOptions.closeTimeout() is exceeded.
        Specified by:
        close in interface java.lang.AutoCloseable

      • closeAsync

        java.util.concurrent.Future<Connection> closeAsync()
        Requests a close of the Connection at the remote and returns a Future that will be completed once the Connection has been fully closed.
        Returns:
        a Future that will be completed when the remote closes this Connection.

      • closeAsync

        java.util.concurrent.Future<Connection> closeAsync​(ErrorCondition error)
        Requests a close of the Connection at the remote and returns a Future that will be completed once the Connection has been fully closed.
        Parameters:
        error - The ErrorCondition to transmit to the remote along with the close operation.
        Returns:
        a Future that will be completed when the remote closes this Connection.
