Class: Syskit::Models::SpecializationManager::SpecializationBlockContext

Inherits:
BasicObject
Defined in:
lib/syskit/models/specialization_manager.rb

Overview

Class used to give a proper evaluation context to the specialization blocks

Its job is to make sure that the composition that is being modified by the specialization block “looks like” the plain composition plus the specialization, regardless of all the other specializations that have been applied

Defined Under Namespace

Classes: Child
