Class Method Details

.Callable(*args) ⇒ Object

Use Callable if you have an operation or any other callable object that does not expose an interface. For example, Trailblazer::Operation::PublicCall#call isn’t compatible with activities, hence you need to decorate it using Callable. The returned object exposes an interface.

Examples:

Create and use a Callable instance.

callable = Trailblazer::Operation::Callable( Memo::Create, call: :__call__ )
callable.( [ctx, {}] ) #=> Activity interface, ::call will invoke Memo::Create.__call__.

Parameters:

• :call (Symbol) —

  Method name to call

• options (Hash) —

  Hash to merge into circuit_options, e.g. :start_task.
