public DepthPredicate(int minDepth,
                      int maxDepth)
```
    Creates a new depth filter for the given depths.
    
    Parameters:
    
    minDepth - the minimal depth
    
    maxDepth - the maximal depth
- Method Detail
  - evaluate
```
public boolean evaluate(Object item)
```
    Matches if the given depth is greater or equal the minimum depth and less or equal the maximum depth and if the call to matches(Item) returns true.
    
    Specified by:
    
    evaluate in interface Predicate
    
    Parameters:
    
    item - some object
    
    Returns:
    
    predicate result

```
protected boolean matches(Item item)
                   throws RepositoryException
```
    Returns true. Subclasses can override to implement something useful that is dependant of the depth.
    
    Parameters:
    
    item - the item to match
    
    Returns:
    
    true if the item matches; false otherwise.
    
    Throws:
    
    RepositoryException - if an error occurs.
