Detailed Description

template<typename vtype>
class schnek::Expression< vtype >

A base type for real time evaluation of mathematical expressions.

Expressions are most commonly constructed from parsing input decks, but might be used elsewhere as function objects.

The expression is templated with the return type. To allow expressions with variables of different type, type promotion operators must be inserted.
