      Specified by:
      getCamelContext in interface org.apache.camel.spi.HasCamelContext

    • setCamelContext

      public void setCamelContext(org.apache.camel.CamelContext camelContext)

    • getTimeout

      public long getTimeout()

    • setTimeout

      public void setTimeout(long timeout)

    • setTimeoutChecker

      public void setTimeoutChecker(long timeoutChecker)
      Time in millis how frequent to check for timeouts. Set this to a lower value if you want to react faster upon timeouts. The default value is 1000.

    • getTimeoutLoggingLevel

      public org.apache.camel.LoggingLevel getTimeoutLoggingLevel()

    • setTimeoutLoggingLevel

      public void setTimeoutLoggingLevel(org.apache.camel.LoggingLevel timeoutLoggingLevel)
      Sets the logging level to use when a timeout was hit.

    • getWorkerPool

      public ExecutorService getWorkerPool()

    • setWorkerPool

      public void setWorkerPool(ExecutorService workerPool)
      To use a shared worker pool for processing timed out requests.

    • getRequestCorrelationId

      public abstract String getRequestCorrelationId(Object request)
      Implement this method to extract the correlation id from the request message body.

    • getResponseCorrelationId

      public abstract String getResponseCorrelationId(Object response)
      Implement this method to extract the correlation id from the response message body.

    • getTimeoutResponse

      public String getTimeoutResponse(String correlationId, Object request)
      Override this to implement a custom timeout response message.
      Parameters:
      correlationId - the correlation id
      request - the request message
      Returns:
      the response message or null to use an ExchangeTimedOutException exception.

    • putState

      public void putState(io.netty.channel.Channel channel, NettyCamelState state)
      Description copied from interface: NettyCamelStateCorrelationManager
      Puts the state.

      You can get access to the Camel message from the NettyCamelState instance.

      Specified by:
      putState in interface NettyCamelStateCorrelationManager
      Parameters:
      channel - the channel
      state - the Camel state to be stored

    • removeState

      public void removeState(io.netty.channel.ChannelHandlerContext ctx, io.netty.channel.Channel channel)
      Description copied from interface: NettyCamelStateCorrelationManager
      Removes the state when the channel is inactive.
      Specified by:
      removeState in interface NettyCamelStateCorrelationManager
      Parameters:
      ctx - netty channel handler context
      channel - the channel

    • getState

      public NettyCamelState getState(io.netty.channel.ChannelHandlerContext ctx, io.netty.channel.Channel channel, Object msg)
      Description copied from interface: NettyCamelStateCorrelationManager
      Gets the state when a response message has been received.

      If the implementation stores the state temporary in for example a Map instance then this method should remove the state from the map as its no longer needed. In other words use the Map.remove(Object) to get and remove the state.

      Specified by:
      getState in interface NettyCamelStateCorrelationManager
      Parameters:
      ctx - netty channel handler context
      channel - the channel
      msg - the response message

    • getState

      public NettyCamelState getState(io.netty.channel.ChannelHandlerContext ctx, io.netty.channel.Channel channel, Throwable cause)
      Description copied from interface: NettyCamelStateCorrelationManager
      Gets the state when some internal error occurred.
      Specified by:
      getState in interface NettyCamelStateCorrelationManager
      Parameters:
      ctx - netty channel handler context
      channel - the channel
      cause - the error
