Method Details

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

isString

default boolean isString()

Description copied from interface: CqnLiteral

Returns true if this is a CqnStringLiteral.

Specified by:

isString in interface CqnLiteral<String>

Returns:

true if this is a string literal, otherwise false
