Included in:
EventGenerator, Relations::Graph
Defined in:
lib/roby/droby/v5/droby_constant.rb

Overview

Generic implementation of the constant-dumping method. This is to be included in all kind of classes which should be dumped by their constant name (for intance Relations::Graph).

Defined Under Namespace

Classes: ConstantResolutionFailed, MismatchingLocalConstant
