end

Instance Method Details

#call(options = {}, flow_options = {}, **circuit_options) ⇒ Object

Note:

Do not override this method as it will be removed in future versions. Also, you will break tracing.

This is the outer-most public ‘call` method that gets invoked when calling `Create.()`. The signature of this is `params, options, *containers`. This was a mistake, as the first argument could’ve been part of ‘options` hash in the first place.

Create.(params, runtime_data, *containers)

#=> Result<Context...>

In workflows/Nested compositions, this method is not used anymore and it might probably get removed in future versions of TRB. Currently, we use Operation::__call__ as an alternative.

Returns:

  • Operation::Railway::Result binary result object

def call(options = {}, flow_options = {}, **circuit_options)
  return call_with_circuit_interface(options, **circuit_options) if options.is_a?(Array) # This is kind of a hack that could be well hidden if Ruby had method overloading. Goal is to simplify the call/__call__ thing as we're fading out Operation::call anyway.

  call_with_public_interface(options, flow_options, **circuit_options)
end

#call_with_circuit_interface(args, **circuit_options) ⇒ signal, [ctx, flow_options]

This interface is used for all nested OPs (and the outer-most, too).

Parameters:

  • args (Array) —

    • Contains [ctx, flow_options]

  • circuit_options (Hash) —

    • Options to configure activity circuit

Returns:

  • (signal, [ctx, flow_options])

TODO: remove when we stop supporting < 3.0.

def call_with_flow_options(options, flow_options)
  raise "[Trailblazer] `Operation.call_with_flow_options is deprecated in Ruby 3.0. Use `Operation.(options, flow_options)`" if Gem::Version.new(RUBY_VERSION) >= Gem::Version.new("3.0.0")

end

#call_with_public_interface(options, flow_options, invoke_class: Activity::TaskWrap, **circuit_options) ⇒ Operation::Railway::Result

Default @activity call interface which doesn’t accept circuit_options

Parameters:

  • args (Array) —

    > [ctx, flow_options]
