Class PageRank.Algorithm

  • Type Parameters:
    V - the graph type
    E - the edge type
    Enclosing class:
    PageRank<V,​E>
    private class PageRank.Algorithm
extends java.lang.Object
    The actual implementation.

    We use this pattern with the inner class in order to be able to cache the result but also allow the garbage collector to acquire all auxiliary memory used during the execution of the algorithm.
