      • apply

        public org.processmining.processtree.ProcessTree apply​(org.processmining.processtree.ProcessTree tree)
        Applies the tree modification to the input tree returning a copy.
        Parameters:
        tree - The tree to be modified.
        Returns:
        A tree where candidates are labeled and split.

      • init

        public void combineCandidates​(org.processmining.processtree.ProcessTree tree)
        Combines all candidates identified before.
        Parameters:
        tree - The tree on which candidates where identified before.

        Sets a subset of children in parallel separating it from the remaining structure.
        Parameters:
        tree - The tree to be modified.
        father - The old father.
        children - The children to be set in parallel with a new father.

      • startIdentifyingCandidates

        public void startIdentifyingCandidates​(org.processmining.processtree.ProcessTree tree)
        Starting function for candidate identification.
        Parameters:
        tree - The tree to be checked.

      • identifyCandidates

        public void identifyCandidates​(org.processmining.processtree.Node node)
        Identifies all candidates according to the candidate check that occur with a shared parallel node as father.
        Parameters:
        node - Node to recurse on.

      • candidateCheck

        public boolean candidateCheck​(org.processmining.processtree.Node node)
        Checks candidates whether they have a candidate property, i.e., if they are a flower or loop structure.
        Parameters:
        node - Node to be checked.
        Returns:
