public HeapNode()
```
- Method Detail
  - step
```
public abstract int step()
```
    Advance to the next node represented by this MultiValuedNodeHeapIterator.HeapNode
    
    Returns:
    
    the next DTM node.
  - cloneHeapNode
```
public MultiValuedNodeHeapIterator.HeapNode cloneHeapNode()
```
    Creates a deep copy of this MultiValuedNodeHeapIterator.HeapNode. The clone is not reset from the current position of the original.
    
    Returns:
    
    the cloned heap node
  - setMark
```
public void setMark()
```
    Remembers the current node for the next call to gotoMark().
  - gotoMark
```
public void gotoMark()
```
    Restores the current node remembered by setMark().
  - isLessThan
```
public abstract boolean isLessThan(MultiValuedNodeHeapIterator.HeapNode heapNode)
```
    Performs a comparison of the two heap nodes
    
    Parameters:
    
    heapNode - the heap node against which to compare
    
    Returns:
    
    true if and only if the current node for this heap node is before the current node of the argument heap node in document order.
  - setStartNode
```
public abstract MultiValuedNodeHeapIterator.HeapNode setStartNode(int node)
```
    Sets context with respect to which this heap node is evaluated.
    
    Parameters:
    
    node - The new context node
    
    Returns:
    
    a MultiValuedNodeHeapIterator.HeapNode which may or may not be the same as this HeapNode.
  - reset
```
public abstract MultiValuedNodeHeapIterator.HeapNode reset()
```
    Reset the heap node back to its beginning.
    
    Returns:
    
    a MultiValuedNodeHeapIterator.HeapNode which may or may not be the same as this HeapNode.
