Detailed Description

template<typename T_Real, typename T_Impl, typename = void>
struct codi::ExpressionMemberOperations< T_Real, T_Impl, typename >

Interface for injecting member operations in expressions

The ExpressionInterface extends from this interface and therefore all methods defined in specializations of this class are available in expressions with the specialized Real type.

E.g. the complex type has the member operations real() and imag(). Which makes the following code possible.

std::complex<double> a,b;
double z = (a + b).real();

In an expression framework, the member operator could be implemented in the AggregatedActiveType specialization for std::complex but this will not make the member operator available in the expression (a+b). The compiler would throw an error that the member operator real() is not available in a BinaryExpression.

By the specialization of this class, member methods can be injected into arbitrary expression implementations. This includes e.g. ActiveType, AggregatedActiveType, BinaryExpression, etc. In the complex case the specialization can be viewed in stdComplex.hpp.

Template Parameters

T_Real	Original primal value of the statement/expression.
T_Impl	Class implementing this interface.
