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.
