  • Constructor Details

    • ReconnectOptions

      public ReconnectOptions()
      Create a new ReconnectOptions instance configured with default configuration settings.

    • ReconnectOptions

      public ReconnectOptions(ReconnectOptions options)
      Creates a ReconnectOptions instance that is a copy of the given instance.
      Parameters:
      options - The ReconnectOptions instance whose configuration should be copied to this one.

  • Method Details

    • clone

      public ReconnectOptions clone()
      Overrides:
      clone in class Object

    • copyInto

      protected ReconnectOptions copyInto(ReconnectOptions other)
      Copy all options from this ReconnectOptions instance into the instance provided.
      Parameters:
      other - the target of this copy operation.
      Returns:
      the ReconnectOptions instance that was given.

    • reconnectEnabled

      public boolean reconnectEnabled()
      Returns true if reconnect is currently enabled for the Connection that these options are assigned to.
      Returns:
      the reconnect enabled configuration state for this options instance.

    • reconnectEnabled

      public ReconnectOptions reconnectEnabled(boolean reconnectEnabled)
      Set to true to enable reconnection support on the associated Connection or false to disable. When enabled a Connection will attempt to reconnect to a remote based on the configuration set in this options instance.
      Parameters:
      reconnectEnabled - Controls if reconnection is enabled or not for the associated Connection.
      Returns:
      this ReconnectOptions instance.

    • addReconnectLocation

      public ReconnectOptions addReconnectLocation(String host, int port)
      Adds an additional reconnection location that can be used when attempting to reconnect the client following a connection failure.
      Parameters:
      host - The host name of the remote host to attempt a reconnection to.
      port - The port on the remote host to use when connecting.
      Returns:
      this ReconnectOptions instance.

    • reconnectLocations

      public List<ReconnectLocation> reconnectLocations()
      Returns:
      an unmodifiable view of the configured reconnect locations.

    • warnAfterReconnectAttempts

      public int warnAfterReconnectAttempts()
      Returns:
      the number of reconnection attempt before the client should log a warning.

    • warnAfterReconnectAttempts

      public ReconnectOptions warnAfterReconnectAttempts(int warnAfterReconnectAttempts)
      Controls how often the client will log a message indicating that a reconnection is being attempted. The default is to log every 10 connection attempts.
      Parameters:
      warnAfterReconnectAttempts - The number of attempts before logging an update about not yet reconnecting.
      Returns:
      this ReconnectOptions instance.

    • maxInitialConnectionAttempts

      public int maxInitialConnectionAttempts()
      Returns:
      the configured maximum number of initial connection attempts to try before giving up

    • maxInitialConnectionAttempts

      public ReconnectOptions maxInitialConnectionAttempts(int maxInitialConnectionAttempts)
      For a client that has never connected to a remote peer before this option controls how many attempts are made to connect before reporting the connection as failed. The default behavior is to use the value of maxReconnectAttempts.
      Parameters:
      maxInitialConnectionAttempts - the maximum number of initial connection attempts to try before giving up.
      Returns:
      this ReconnectOptions instance.

    • maxReconnectAttempts

      public int maxReconnectAttempts()
      Returns:
      the configured maximum number of reconnection attempts to try before giving up

    • maxReconnectAttempts

      public ReconnectOptions maxReconnectAttempts(int maxReconnectionAttempts)
      The number of reconnection attempts allowed before reporting the connection as failed to the client. The default is no limit or (-1).
      Parameters:
      maxReconnectionAttempts - the maximum number of reconnection attempts to try before giving up.
      Returns:
      this ReconnectOptions instance.

    • reconnectDelay

      public int reconnectDelay()
      Returns:
      the configured reconnect delay to use after between attempts to connect or reconnect.

    • reconnectDelay

      public ReconnectOptions reconnectDelay(int reconnectDelay)
      Controls the delay between successive reconnection attempts, defaults to 10 milliseconds. If the back off option is not enabled this value remains constant.
      Parameters:
      reconnectDelay - The reconnect delay to apply to successive attempts to reconnect.
      Returns:
      this ReconnectOptions instance.

    • maxReconnectDelay

      public int maxReconnectDelay()
      Returns:
      the configured maximum reconnect attempt delay allowed when using delay back off scheduling.

    • maxReconnectDelay

      public ReconnectOptions maxReconnectDelay(int maxReconnectDelay)
      The maximum time that the client will wait before attempting a reconnect. This value is only used when the back off feature is enabled to ensure that the delay does not grow too large. Defaults to 30 seconds as the max time between successive connection attempts.
      Parameters:
      maxReconnectDelay - The maximum interval allowed when connection attempt back off is in effect.
      Returns:
      this ReconnectOptions instance.

    • useReconnectBackOff

      public boolean useReconnectBackOff()
      Returns:
      if the reconnection attempts will be delayed using a back off multiplier.

    • useReconnectBackOff

      public ReconnectOptions useReconnectBackOff(boolean useReconnectBackOff)
      Controls whether the time between reconnection attempts should grow based on a configured multiplier. This option defaults to true.
      Parameters:
      useReconnectBackOff - should connection attempts use a back off of the configured delay.
      Returns:
      this ReconnectOptions instance.

    • reconnectBackOffMultiplier

      public double reconnectBackOffMultiplier()
      Returns:
      the multiplier used when the reconnection back off feature is enabled.

    • reconnectBackOffMultiplier

      public ReconnectOptions reconnectBackOffMultiplier(double reconnectBackOffMultiplier)
      The multiplier used to grow the reconnection delay value, defaults to 2.0d.
      Parameters:
      reconnectBackOffMultiplier - the delay multiplier used when building delay between reconnection attempts.
      Returns:
      this ReconnectOptions instance.
