- Method Detail
  - isRef
```
default boolean isRef()
```
    Description copied from interface: CqnSource
    
    Returns true if this is a CqnStructuredTypeRef.
    
    Specified by:
    
    isRef in interface CqnSource
    
    Returns:
    
    true if this is a structured type reference, otherwise false
  - asRef
```
default CqnStructuredTypeRef asRef()
```
    Description copied from interface: CqnSource
    
    Casts this CQN source to CqnSelect.
    
    Specified by:
    
    asRef in interface CqnSource
    
    Returns:
    
    this CQN source as a CqnSelect
  - alias
```
Optional<String> alias()
```
    Specified by:
    
    alias in interface CqnReference
  - 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
