  - accept
```
default void accept(CqnVisitor visitor)
```
    Description copied from interface: CqnToken
    
    Traverses the expression tree represented by this token with a given visitor. The traversal order is depth-first. If this token has child nodes they are traversed first by dispatching the visitor to the children's accept methods. Afterwards this token is passed to the visitor's visit method specific for this token's type.
    
    Specified by:
    
    accept in interface CqnToken
    
    Parameters:
    
    visitor - the CqnVisitor
