class hornet.contrib.networkabstractor.NetworkAbstractionPlugin(data_provider, builder_cls=<class 'hornet.contrib.networkabstractor.NetworkAbstractor'>)

Plugin that transforms from one level to another level. Returns the provider attribute to be set to an instance of a valid implementation of hornet.plugin.abstractor.AttributeProvider.

class hornet.contrib.networkabstractor.NetworkAbstractor(provider, original_graph)

Abstracts the graph according to the abstractor function. The abstract replaces the nodes by the abstract values and aggregates the results (size element) for each unique abstract node. Does not modify the input graph.

The abstractor function should take a node as input and provide some level of abstraction based upon that node. It must return a list of ids for new abstracted nodes (even for a single element).
