Class: OpenC3::TargetModel

Inherits:
Model show all
Defined in:
lib/openc3/models/target_model.rb

Overview

Manages the target in Redis. It stores the target itself under the __openc3_targets key under the target name field. All the command packets in the target are stored under the __openc3cmd__ key and the telemetry under the __openc3tlm__ key. Any new limits sets are merged into the __limits_sets key as fields. Any new limits groups are created under __limits_groups with field name. These Redis key/fields are all removed when the undeploy method is called.
