stefanv This class serves as a generic topology class capable of representing almost any topology. It is basically a multidimensional collection of NeuronConfig objects. NeuronConfig objects are used to configure NeuronPipeline objects (Flyweight design pattern). A Typical NN would have about 3 or so NeuronPipelines i.e. Sigmoid, linear and Bias unit. GenericTopologyVisitor objects are used to access NeuronConfig objects in a "left-to-right, top-to-bottom" fashion. The Observer Pattern in also supported - clients just need to register. This class forms part of the Generic Framework and may be extended if needed. It should work "as-is" in most cases. There is also a getLayerIterator() method to manually traverse layers (NeuronConfig objects).
