NAME¶
Path - record of connectors visited during dataflow
SYNOPSIS¶
#include <Unidraw/path.h>
DESCRIPTION¶
A Path object stores a record of connectors that have been visited during
dataflow. Transfer functions, state variables, connectors, and other
components can use the information in the path to determine whether data
should be transmitted, for example, to avoid circular flow.
PUBLIC OPERATIONS¶
- Path(Path* = nil)
- Instantiate a new path, optionally with a duplicate of the information
contained in the given path.
- virtual void Visit(Connector*)
- Register a connector as having been visited.
- virtual boolean Visited(Connector*)
- Return whether or not a connector has been registered previously with the
path.
