public SelfContext(EvalContext parentContext,
           NodeTest nodeTest)
```
    Create a new SelfContext.
    
    Parameters:
    parentContext - EvalContext
    nodeTest - guard
- Method Detail
  - getSingleNodePointer
```
public Pointer getSingleNodePointer()
```
    Description copied from class: EvalContext
    
    Returns the first encountered Pointer that matches the current context's criteria.
    
    Overrides:
    
    getSingleNodePointer in class EvalContext
    
    Returns:
    Pointer
  - getCurrentNodePointer
```
public NodePointer getCurrentNodePointer()
```
    Description copied from class: EvalContext
    
    Returns the current context node. Undefined before the beginning of the iteration.
    
    Specified by:
    
    getCurrentNodePointer in class EvalContext
    
    Returns:
    NodePoiner
  - nextNode
```
public boolean nextNode()
```
    Description copied from class: EvalContext
    
    Returns true if there is another object in the current set. Switches the current position and node to the next object.
    
    Specified by:
    
    nextNode in class EvalContext
    
    Returns:
    boolean
  - reset
```
public void reset()
```
    Description copied from class: EvalContext
    
    Sets current position = 0, which is the pre-iteration state.
    
    Overrides:
    
    reset in class EvalContext
  - setPosition
```
public boolean setPosition(int position)
```
    Description copied from class: EvalContext
    
    Moves the current position to the specified index. Used with integer predicates to quickly get to the n'th element of the node set. Returns false if the position is out of the node set range. You can call it with 0 as the position argument to restart the iteration.
    
    Overrides:
    
    setPosition in class EvalContext
    
    Parameters:
    position - to set
    
    Returns:
    boolean
