Implementations will usually walk up the node tree to find the semantic object. As the node model structure does not reflect the containment structure of the semantic object graph, clients should usually use the utilities in NodeModelUtils to obtain the semantic instance.
    
    Specified by:
    
    getSemanticElement in interface INode
    
    Returns:
    
    the nearest semantic object that is associated with the subtree of this node. May return null.

    Specified by:
    
    getAsTreeIterable in interface INode
    
    Returns:
    
    a tree iterable where this node represents the root instance.

    Specified by:
    
    getLeafNodes in interface INode
    
    Returns:
    
    an iterable for all contained leaf nodes. Never null.
  - reverse
```
public BidiTreeIterable<INode> reverse()
```
    Description copied from interface: BidiTreeIterable
    Returns a reverse version of this iterable that can be used forwards and backwards. In other words, an iterator provided by the reverse iterable will delegate its hasNext() and next() invocations to BidiIterator.hasPrevious() and BidiIterator.previous() respectively.
    
    This allows clients to iterate backwards by means of the enhanced for-loop:
    
    for(T t: iterable.reverse()) { // do something with t }
    Specified by:
    
    reverse in interface BidiIterable<INode>

    Returns:
    
    the number of tokens that the parser had to peek before it could decide to create this node.
