Method Details
- add
  
  public void add(Op op)
  
  Accumulate an op in the OpN. This exists to help building OpN in the first place. Once built, an OpN, like any Op should be treated as immutable with no calls change the sub ops contents. No calls to .add.
- get
  
  public Op get(int idx)
- apply
  
  public abstract Op apply(Transform transform, List<Op> elts)
- copy
  
  public abstract OpN copy(List<Op> elts)
- size
  
  public int size()
- hashCode
  
  public int hashCode()

  hashCode in class OpBase
- getElements
  
  public List<Op> getElements()
- iterator
