Core Classes
============

.. currentmodule:: pyomo.core.expr.numeric_expr

The following are the two core classes documented here:

   * :class:`NumericValue`
   * :class:`NumericExpression`

The remaining classes are the public classes for expressions, which
developers may need to know about. The methods for these classes are not
documented because they are described in the
:class:`NumericExpression` class.

Sets with Expression Types
--------------------------

The following sets can be used to develop visitor patterns for 
Pyomo expressions.
