• Generate .node.json from C++ Node API

When implementing an application the only C++ code involved is within nodes. Graphlets and applications don't have any C++ code (see the design workflow).

C++ Nodes

Each C++ node must implement the interface described in dw::framework::NodeConcept. This tutorial walks through the different parts of the API and how to implement them.

Generate .node.json from C++ Node API

From C++ Node to JSON Node Descriptor

The nodedescriptor command line tool can generate a .node.json file based on the information provided by the nodes API. The previously referenced tutorial describes how the tool can be invoked. It requires the C++ code of the node to be compiled into a shared object (.so).
