Examples of AffinityGraphBuilder

com.sun.sgs.impl.service.nodemap.affinity.graph.AffinityGraphBuilder
Graph builder interface. Graph builder objects take task access information and create a graph from it, and can return the graph. Builders are also responsible for instantiating the objects which will consume the graph.
The returned graph vertices are identities, and the edges are the object references the vertices have in common. Edge weights refer to the number of common references of all objects (e.g. if obj1 is used twice by both objects, the weight is 2. If both objects then use obj2, the weight becomes 3). Parallel edges are not supported.
Graphs are pruned as time goes by, both to ensure that endless resources are not consumed, and to ensure that while the graph contains enough history to be useful, it doesn't contain too much very old history.
The graphs contain only application information (no system service information) to limit the size of the graphs.
Graph builders are typically instantiated by the node {@link GraphListener}. In order to be instantiated by the {@code GraphListener}, they should implement a constructor taking the arguments {@code (Properties, ComponentRegistry, TransactionProxy)}. The transaction proxy can be {@code null} for testing outside of theDarkstar service framework.
