• setConceptuallyUnrooted

  public void setConceptuallyUnrooted​(boolean intent)

• 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.

  Specified by:

  conceptuallyUnrooted in interface RootedTree

  true if tree(s) are to be viewed as unrooted
