public PathConstraintBag(java.lang.String path,
                         ConstraintOp op,
                         java.lang.String bag)
```
    Constructs a new PathConstraintBag. The path should be a normal path expression with dots separating the parts. Do not use colons to represent outer joins, and do not use square brackets to represent subclass constraints. The path will be checked for format, but can only be verified once inside a PathQuery object by the PathQuery.verifyQuery() method. This object is used to form a constraint to a bag.
    
    Parameters:
    
    path - the path that the constraint is attached to
    
    op - the type of operation
    
    bag - the name of the bag to constrain to
    
    Throws:
    
    java.lang.NullPointerException - if path, op, or bag are null
    
    java.lang.IllegalArgumentException - if the path contains colons or square brackets, or is otherwise in a bad format, or if the op is invalid for this constraint type
