      public void check() throws PreconditionException
      Description copied from interface: Algorithm
      Checks whether all preconditions of the current graph are satisfied.
      Specified by:
      check in interface Algorithm
      Overrides:
      check in class AbstractAlgorithm
      Throws:
      PreconditionException - if the preconditions of the current graph are not satisfied.

    • getDescription

      public String getDescription()
      Description copied from class: AbstractAlgorithm
      The algorithm description.
      Specified by:
      getDescription in interface Algorithm

      public boolean rootedTree​(Node rootNode)
      Check whether the tree is rooted.

    • getParameters

      public Parameter[] getParameters()
      Description copied from interface: Algorithm
      Returns a list of Parameter that are set for this algorithm.
      Specified by:
      getParameters in interface Algorithm
