AsyncNodeBody Requirements: Pseudo-Signature, Semantics
-
Body::~Body()#
Destructor.
-
void Body::operator()(const Input &v, GatewayType &gateway)#
Requirements:
The
Input
type must be the same as theInput
template type argument of theasync_node
instance in which theBody
object is passed during construction.The
GatewayType
type must be the same as thegateway_type
member type of theasync_node
instance in which theBody
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.
