Detailed Description

Singleton registries for custom reducers, conditions, and node types.

These registries are used during graph compilation (GraphEngine::compile) to resolve JSON-defined reducer names, condition names, and node type names into their corresponding functions and factories.

Built-in entries are registered automatically. Users can add custom entries before compiling a graph.

Typedef Documentation

NodeFactoryFn

using neograph::graph::NodeFactoryFn = typedef std::function<std::unique_ptr<GraphNode>( const std::string& name, const json& config, const NodeContext& ctx)>

Factory function signature for creating graph nodes.

Parameters

name	Node name within the graph.
config	Node-specific configuration from the JSON definition.
ctx	Node context with provider, tools, and model.

Returns

A unique_ptr to the created GraphNode.
