## Definition

The class `Apollonius_graph_vertex_base_2` provides a model for the `ApolloniusGraphVertexBase_2` concept which is the vertex base required by the `ApolloniusGraphDataStructure_2` concept.

The class `Apollonius_graph_vertex_base_2` has two template arguments, the first being the geometric traits of the Apollonius graph and should be a model of the concept `ApolloniusGraphTraits_2`. The second is a Boolean which controls whether hidden sites are actually stored. Such a control is important if the user is not interested in hidden sites and/or if only insertions are made, in which case no hidden site can become visible. If `StoreHidden` is set to `true`, hidden sites are stored, otherwise they are discarded. By default `StoreHidden` is set to `true`.

Is Model Of:
  `ApolloniusGraphVertexBase_2`
