Description
-----------

Provides accessors for expressions.

This module wraps the expressions derived from ``suite.Expression`` using the classes
corresponding to the XSCADE serialization, as exposed in the SCADE documentation:
``SCADE Suite Metamodels for Java API > 12. Scade Language Metamodels > Expressions``.
These classes allow accessing precisely each member of an expression.

Use the :py:func:`~ansys.scade.apitools.expr.access.accessor` function to create
an accessor from any SCADE Suite expression.
