Class: OpenC3::TableConfig

Inherits:
PacketConfig show all
Defined in:
lib/openc3/tools/table_manager/table_config.rb

Overview

Processes the Table Manager configuration files which define tables. Since this class inherits from PacketConfig it only needs to implement Table Manager specific keywords. All tables are accessed through the table and tables methods.
