  - getPaths
```
Collection<List<? extends TreeNode>> getPaths()
```
    Returns the complete set of rooting paths for this context element.
    
    Returns:
    
    the set of rooting paths
  - getContext
```
ContextElement getContext()
```
    Returns the context information associated with this node.
    
    Returns:
    
    node context information
  - toTreeString
```
String toTreeString()
```
