This class extends upon PropertyInterface, and adds type-safe methods to get and set the node and edg...
Abstracts the computation of minimal and maximal values on node and edge values of properties...
PropertyInterface describes the interface of a graph property.
The edge struct represents an edge in a Graph object.
Definition: Edge.h:39
The node struct represents a node in a Graph object.
Definition: Node.h:39
A graph property that maps a double value to graph elements.
Event is the base class for all events used in the Observation mechanism.
Definition: Observable.h:47
Interface all numerical properties. Property values are always returned as double.
Base class for computing values on meta nodes and edges.
A graph property that maps a std::vector<double> value to graph elements.
