This class extends upon PropertyInterface, and adds type-safe methods to get and set the node and edg...
PropertyInterface describes the interface of a graph property.
The edge struct represents an edge in a Graph object.

The node struct represents a node in a Graph object.
Definition: Node.h:39
A graph property that maps a tlp::Graph* value to graph elements.
Definition: GraphProperty.h:39
Event is the base class for all events used in the Observation mechanism.
Definition: Observable.h:47
unsigned int id
id The identifier of the node.
Definition: Node.h:43
unsigned int id
id The identifier of the edge.
