Detailed Description

PropertyInterface describes the interface of a graph property.

The intent of a property is to hold a value for each node and edge (e.g. the degree of the nodes).

A property can be used in two different ways : Either it is attached to a graph; and in this case creating and deleting the property is handled by the graph (

See also
Graph::getProperty()).

Either is is detached from a graph, and you have to handle creation and deletion yourself. This is most useful for some algorithms that need a temporary property, but do not want the property to appear on the graph after the computation.
