- Method Detail
  - preVisit
```
void preVisit(@Nonnull
              T object)
```
    Visits an object. This method is called before visiting children (pre-order).
    
    Parameters:
    
    object - the visited object
  - visit
```
void visit(@Nonnull
           T object)
```
    Visits an object. This method is actually called just after preVisit(Object), it makes sense to implement it when you don't need to distinguish between pre-order and post-order traversal.
    
    Parameters:
    
    object - the visited object
  - postVisit
```
void postVisit(@Nonnull
               T object)
```
    Visits an object. This method is called after visiting children (post-order).
    
    Parameters:
    
    object - the visited object
  - getValue
```
@Nonnull
R getValue()
    throws NotFoundException
```
    Returns the value of this visitor.
    
    Returns:
    
    the value
    
    Throws:
    
    NotFoundException - when no value has been found
