Detailed Description

template<typename T_Tape, typename T_Impl>
struct codi::ActiveTypeBase< T_Tape, T_Impl >

Represents the base implementation concrete lvalue in the CoDiPack expression tree.

The class uses members for storing the value and the identifier.

See Expression design documentation for details about the expression system in CoDiPack.

The storage of the underlying tape and the access to it is left to the implementing class.

Template Parameters

T_Tape	The tape that manages all expressions created with this type.
T_Impl	Implementing class.
