Method Details

left

CqnValue left()

right

CqnValue right()

operator

CqnArithmeticExpression.Operator operator()

isArithmeticExpression

default boolean isArithmeticExpression()

Description copied from interface: CqnExpression

Returns true if this is a CqnArithmeticExpression.

Specified by:

isArithmeticExpression in interface CqnExpression

Returns:

true if this is an arithmetic expression, otherwise false

asArithmeticExpression

default CqnArithmeticExpression asArithmeticExpression()

Description copied from interface: CqnExpression

Casts this expression to a CqnArithmeticExpression.

Specified by:

asArithmeticExpression in interface CqnExpression

Returns:

this as an arithmetic expression

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 CqnExpression

Specified by:

accept in interface CqnToken

Parameters:

visitor - the CqnVisitor
