class Syskit::Models::SpecializationManager::SpecializationBlockContext

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

Attributes

model[R]

The final composition model (i.e. the one on which the specialization is being applied)

overload_info[R]

The overload information

@return [Models::FacetedAccess]

reference_model[R]

The composition model that is made of the root model and only the relevant specialization applied
