operator()()

template<typename D , typename V , typename... Ts>

template<typename... Args>

graph_node<D> graph_observe_node_construct< D, V, Ts >::operator() ( Args &&...  args )

inline

Constructs a observed graph node based on passed parent nodes or values.

The arity of this operator should have the same arity as one of the constructors of D or compilation will fail. The passed arguments can either be of the base type required by the constructor of D or can be of type graph_node_t<T> where T is one of the base types required by the constructor of D. The arguments are evaluated from left to right.

Template Parameters

Args	Types of arguments to pass to the constructor of D

Parameters

args	arguments to pass to the constructor of D

Returns

graph_node<D>
