All Implemented Interfaces:
Graph, RootedTree, Tree, Attributable

public class RootedFromUnrooted extends AbstractRootedTree
Root an unrooted tree. This class works as a wrapper over any tree to root it. There are two constructors, one which roots the tree at any internal node, the other roots the tree between any two internal nodes. Be aware that rooting between nodes where one of them has less than 3 adjacencies may be problematic when converting back from the Newick format.

      the parent node of the given node, or null if the node is the root node.
    • getRootNode

      public Node getRootNode()
      Description copied from interface: RootedTree
      The root of the tree has the largest node height of all nodes in the tree.
      Returns:
      the root of the tree.
    • conceptuallyUnrooted

      public boolean conceptuallyUnrooted()
      Description copied from interface: RootedTree
      Due to current implementation limitations, trees store "branch" information in nodes. So, internally rooted trees are genetrated when un-rooted would be more natural. This should be removed. If this is a rooted tree then it is rooted. This can really only confuse things. Trees are unrooted, RootedTrees are rooted. This is not an implementation limitation. It may be that a RootedTree has an arbitrary root but it is still rooted. With a rooted tree, it is convenient to store branch information at the node (i.e., for the branch above the node) because there is no "branch" object. Andrew. This function will probably become deprecated once the "development" tree viewer becomes in sync with the main tree viewer branch and some method of handling this concept has been introduced. Until then, this method remains.
      Returns:
      true if tree(s) are to be viewed as unrooted
