Detailed Description

template<typename Derived_T, int N_Dims>
struct ltl::ExprBase< Derived_T, N_Dims >

Base class for all operands in expression templates. Both nodes and leafs of expressions inherit from this type.

This class uses the Curiously Recurring Template Pattern (CRTP) to implement "compile-time polymorphism" by taking the derived type as a template parameter and providing a method derived() to cast itself to the derived type.

The rank of the expression operand is made explicit through the second template parameter N_Dims to allow strict type checking on the rank in functions that accept ExprBase objects as parameters (e.g. make sure that parameters have the same rank, or some predetermined rank).
