- Method Detail
  - getSplits
```
public static SplitSystem getSplits(Tree tree)
```
    creates a split system from a tree (using tree-induced order of sequences)
    
    Parameters:
    
    tree -
  - getSplits
```
public static SplitSystem getSplits(java.util.List<Taxon> taxa,
                                    Tree tree)
```
    creates a split system from a tree (using a pre-specified order of sequences)
    
    Parameters:
    
    taxa - the list of taxa (order is important)
    
    tree -
  - getSplit
```
public static void getSplit(java.util.List<Taxon> taxa,
                            Tree tree,
                            Edge edge,
                            boolean[] split)
```
    get split for branch associated with internal node
    
    Parameters:
    
    taxa - order of labels
    
    tree - Tree
    
    edge - Edge
    
    split -
  - isSame
```
public static boolean isSame(boolean[] s1,
                             boolean[] s2)
```
    Checks two splits for identity. This method assumes that the two splits are of the same length and use the same leaf order/
    
    Parameters:
    
    s1 - split 1
    
    s2 - split 2
    
    Returns:
    
    true if the two splits are identical
    
    Throws:
    
    java.lang.IllegalArgumentException - if splits don't have the same length
