    • interceptProperties

      public void interceptProperties(Map<String,Object> properties)
      Description copied from interface: PropertiesInterceptor
      Intercept method invocation arguments used to find and invoke API method. Can be overridden to add custom/hidden method arguments.
      Specified by:
      interceptProperties in interface PropertiesInterceptor
      Parameters:
      properties - method invocation arguments.

    • doInvokeMethod

      protected Object doInvokeMethod(ApiMethod method, Map<String,Object> properties) throws org.apache.camel.RuntimeCamelException
      Invoke the API method. Derived classes can override, but MUST call super.doInvokeMethod().
      Parameters:
      method - API method to invoke.
      properties - method arguments from endpoint properties and exchange In headers.
      Returns:
      API method invocation result.
      Throws:

      Parameters:
      result - API method invocation result
      Returns:
      either the same result if it cannot be split, an array or collection object with split results

    • interceptResult

      public void interceptResult(Object methodResult, org.apache.camel.Exchange resultExchange)
      Description copied from interface: ResultInterceptor
