    • fuse0

      protected void fuse0(MoleculeGraph graph, boolean check)
      Add those nodes and edges of a graph that are not already elements. If the graph has an atom connected to a reactant or product, then also adds the graph to that structure. Handles one connected component.
      Overrides:
      fuse0 in class Molecule
      Parameters:
      graph - the structure to fuse into this one
      check - true if a containment check should be performed to ensure that only those nodes and edges are added that are not already elements - false if the graph is known to be disjoint from this graph and this check can be safely skipped
