Method Details

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
