    • getSetCategory

      public Set<Category> getSetCategory()
      Description copied from interface: Algorithm
      Returns a set of categories to classify this algorithm . e.g. return new HashSet(Arrays.asList( Category.GRAPH, Category.NODE )); is an algorithm, working on graphs and more specific on nodes
      Specified by:
      getSetCategory in interface Algorithm
      Overrides:
      getSetCategory in class AbstractAlgorithm
      Returns:
      Set of Category Enums that classify this algorithm.

      Specified by:
      check in interface Algorithm
      Overrides:
      check in class AbstractAlgorithm
      Throws:
      PreconditionException - if the preconditions of the current graph are not satisfied.
