Defined in:
lib/generators/camunda/bpmn_classes/bpmn_classes_generator.rb

Overview

Parses the BPMN file and creates task classes according to the ID of the process file and the ID of each task. It checks each task and only creates it if the topic name is the same as the process ID. This allows one to have some tasks be handled outside the Rails app. It confirms that the ID’s are valid Ruby constant names.
