AsyncNodeBody

[req.async_node_body]

A type Body satisfies AsyncNodeBody if it meets the following requirements:

AsyncNodeBody Requirements: Pseudo-Signature, Semantics

Body::Body(const Body&)

Copy constructor.

Body::~Body()

Destructor.

void Body::operator()(const Input &v, GatewayType &gateway)

Requirements:

  • The Input type must be the same as the Input template type argument of the async_node instance in which the Body object is passed during construction.

  • The GatewayType type must be the same as the gateway_type member type of the async_node instance in which the Body object is passed during construction.

The input value v is submitted by the flow graph to an external activity. The gateway interface allows the external activity to communicate with the enclosing flow graph.
