m2isar.metamodel.utils.ExprMutator
==================================

.. py:module:: m2isar.metamodel.utils.ExprMutator

.. autoapi-nested-parse::

   A helper module for applying all expression visitor functions in this package to
   functions and instructions to get rid of monkey patching and use instead polymorphism.

   .. autoapi-inheritance-diagram:: m2isar.metamodel.utils.ExprMutator.ExprMutator
      :parts: 1
      :private-bases:


   Base class for recursive metamodel traversal with 2 modes:
       - Generating text by appending context while traversing AST.
       - Analyzing/Mutating the AST (sometimes with the help of a context) and returning a modified AST.
   To implement a new mutator, overload the 'generate' method of nodes that need altered visitation behavior.
   Use self for additonal global state information
   Use context for stack-based information that is only relevant for the current branch of the AST.
