Listing 2.

Dynamic selection of container class in dependence on number of connections. The simulation engine executes this procedure every time it stores a single connection from source to target. The listing states the algorithm in pseudocode close to the C++ implementation. The angle brackets enclose integer template arguments. These enable access to different implementations of the class through specialization. For simplicity the code assumes that the Connector is homogeneous before and after the new connection is added. Furthermore, the connector stores only target, the downstream GID, neglecting potential further parameters of the connection such as weight and delay.
