#add_measure(instance_name, instance_display_name, path_to_measure, measure_metadata) ⇒ Object

Add a measure from the custom hash format without reading the measure.rb or measure.json file

Parameters:

  • path_to_measure (String) —

    This is the local path to the measure directory, relative or absolute. It is used when zipping up all the measures.

  • measure_metadata (Hash) —

    Format of the measure.json

Returns:

  • (Object) —

    Returns the measure that was added as an OpenStudio::AnalysisWorkflowStep object

  @items.last
end

#add_measure_from_excel(measure) ⇒ Object

Add a measure from the format that Excel parses into. This is a helper method to map the excel data to the new programmatic interface format

Returns:

  • (Object) —

#add_measure_from_path(instance_name, instance_display_name, path_to_measure) ⇒ Object

Add a measure to the workflow from a path. Inside the path it is expecting to have a measure.json file if not, the BCL gem is used to create the measure.json file.

Parameters:

  • path_to_measure (String) —

    This is the local path to the measure directory, relative or absolute. It is used when zipping up all the measures.

Returns:

  • (Object) —

    Returns the measure that was added as an OpenStudio::AnalysisWorkflowStep object
