class URBANopt::Scenario::ScenarioCSV
Public Class Methods
ScenarioCSV
is a ScenarioBase
which assigns a Simulation Mapper to each Feature in a FeatureFile using a simple CSV format. The CSV file has three columns 1) feature_id, 2) feature_name, and 3) mapper_class_name. There is one row for each Feature.
- parameters:
-
name
- String - Human readable scenario name. -
root_dir
- String - Root directory for the scenario, contains Gemfile describing dependencies. -
run_dir
- String - Directory for simulation of this scenario, deleting run directory clears the scenario. -
feature_file
- URBANopt::Core::FeatureFile - FeatureFile containing features to simulate. -
mapper_files_dir
- String - Directory containing all mapper class files containing MapperBase definitions. -
csv_file
- String - Path to CSV file assigning a MapperBase class to each feature in feature_file. -
num_header_rows
- String - Number of header rows to skip in CSV file.
