Abstraction.StackedSourceSignature of stacked domains
The signature STACKED is the feature-complete signature in Mopsa. It represents the lowlevel unified signature used by the framework and all other signatures are casted to it during the construction of the top-level abstraction.
In addition to the access to the top-level abstraction through the manager, this signature allows performing unification over a (shared) sub-abstraction during lattice operations (subset, join, meet and widen).
