Module: Trailblazer::Activity::TaskWrap::VariableMapping

Defined in:
lib/trailblazer/activity/task_wrap/variable_mapping.rb

Overview

Creates taskWrap steps to map variables before and after the actual step. We hook into the Normalizer, process ‘:input` and `:output` directives and translate them into a DSL::Extension.

Note that the two options are not the only way to create filters, you can use the more low-level Scoped() etc., too, and write your own filter logic.

end

.merge_for(input, output, id:) ⇒ Object

DISCUSS: do we want the automatic wrapping of input and output?
