Class GraphAttribute<T>

Namespace

Graph1x.Serialization

Assembly

Graph1x.dll

A named, typed attribute read off a vertex or edge during export — the same declaration drives GraphML (typed <key> elements) and node-link JSON (typed properties). A null string value omits the attribute on that element. Names must be unique per element kind and must not collide with structural names (id, source, target, or the weight key when a weight selector is set).

public sealed class GraphAttribute<T>

Type Parameters

T

The vertex or edge type the attribute reads from.
