Detailed Description

template<typename Expr>
struct codi::ExpressionTraits::NumberOfOperations< Expr >

Counts the number of nodes in the expression.

Member Function Documentation

◆ node()

template<typename Expr >
template<typename Node >
static size_t constexpr codi::ExpressionTraits::NumberOfOperations< Expr >::node ( )
inlinestaticconstexpr

Called for each node in the expression.

Implementations can call the toLinks method in order to evaluate all links of the node.

Must be a constexpr.

Default: Call each link of the node and forward all arguments.
